Item Autopsy report of a case of perinatal AIDS.(1994-12-01) Lanjewar, D N; Maheshwari, M B; Khanna, S AItem Bilateral renal angiomyolipoma in association with tuberous sclerosis.(1997-07-01) Lanjewar, D N; Jain, P; Maheshwari, M B; Setty, C RRenal angiomyolipoma with tuberous sclerosis has not yet been reported in Indian literature. We report a case of bilateral angiomyolipoma associated with tuberous sclerosis in a 25 year old man.Item Childhood sarcoid myopathy manifesting as joint contractures.(1996-02-01) Lanjewar, D N; Maheshwari, M B; Lakhani, S N; Patel, R B; Holla, V VItem Coexistent lymphoma with tuberculosis and Kaposi's sarcoma with tuberculosis occurring in lymph node in patients with AIDS: A report of two cases.(2010-07) Lanjewar, D N; Lanjewar, Sonali D; Chavan, GajananAlthough there have been a few reports of simultaneous infections and neoplasm in patients with acquired immune deficiency syndrome, no reports of coexistent lymphoma with tuberculosis and Kaposi's sarcoma with tuberculosis occurring in the same lymph node have been described. In this article, we describe coexistent lymphoma with tuberculosis in one case and Kaposi's sarcoma with tuberculosis in another case of human immune deficiency virus-infected individuals.Item Cryptosporidium, isospora and strongyloides in AIDS.(1996-01-01) Lanjewar, D N; Rodrigues, C; Saple, D G; Hira, S K; DuPont, H LBACKGROUND: Diarrhoea is a common presentation in patients with AIDS. It occurs due to a number of parasites which are seldom seen in immunocompetent hosts. METHODS: Between January 1993 and July 1994, faecal specimens from 77 patients with AIDS presenting with diarrhoea of more than a month's duration were examined by direct wet mount microscopy of saline and iodine preparations and by the modified Ziehl-Neelsen stain. RESULTS: Cryptosporidium, Isospora and Strongyloides stercoralis alone or in combination were present in 29 of the 77 patients. CONCLUSION: The presence of these parasites highlights their pathogenic potential for immunocompromised patients with AIDS. Diarrhoea due to Isosporais responsive to treatment, hence their identification has therapeutic implications as well.Item Hepatic perforation due to ascariasis.(1993-05-01) Lanjewar, D N; Maheshwari, M B; Wagholikar, U LItem Kaposi's sarcoma in a patient with AIDS.(2008-04-16) Kura, M M; Khemani, U N; Lanjewar, D N; Raghuwanshi, S R; Chitale, A R; Joshi, Shashank RWe report a case of a 40 year old HIV infected male, citizen of Somalia who presented with multiple painful, livid reddish brown plaques, papules and nodules on both lower limbs and purplish red nodules on the hard palate. The cutaneous nodular lesions on biopsy showed characteristic features of Kaposi's sarcoma. This case is reported due to paucity of Kaposi's sarcoma in Indian literature.Item Kaposi's sarcoma with thrombocytopenia in a heterosexual Asian Indian male.(2005-05-30) Shenoy, V V; Joshi, Shashank R; Duberkar, D; Kadam, K N; Shedge, R T; Lanjewar, D NA 45-year-old heterosexual male patient with retroviral disease since 12 years presented with hyperpigmented lesions, misdiagnosed initially as purpura due to an associated thrombocytopenia, but was biopsy proven to be Kaposi's sarcoma (KS). Bone marrow examination revealed excess megakaryocytes. Low CD4 count and absence of platelet specific IgG reduced the likelihood of immune thrombocytopenia (ITP). However after 6 weeks of antiretroviral therapy the patient's lesions have reduced and platelet counts are improving, possibly suggesting a sequestration thrombocytopenia in the abnormal tumor vessels of KS.Item Metastatic carcinoma in hepatic hemangioma.(2000-07-24) Lanjewar, D N; Nambiar, A; Jain, PMetastasis into the hepatic hemangioma is a rare occurrence. We report a unique case of metastasis of intestinal carcinoma into hepatic hemangioma in a case of 65 year old male who presented with anorexia, weakness and headache. The postmortem examination revealed adenocarcinoma in the ileocaecal region. The liver showed a subcapsular hemangioma of 1.5 cms. diameter which on microscopic examination revealed metastasis of adenocarcinoma. The is the first documentation of metastasis in hepatic hemangioma. Such cases may pose problems of diagnostic difficulties and thus may result in mismanagement.Item Metastatic carcinoma in uterine leiomyoma.(1997-07-01) Lanjewar, D N; Shetty, C RMetastasis of tumours are known to occur in the rarest of sites in the human body. But one of the truly rare phenomena in surgical pathology is to find the metastasis of one tumour into another. We report one such case of metastatic carcinoma in uterine leiomyoma from an occult primary site.Item The natural history of human immunodeficiency virus infection among adults in Mumbai.(2003-05-22) Hira, Subhash K; Shroff, H J; Lanjewar, D N; Dholkia, Y N; Bhatia, Vandana P; Dupont, H LBACKGROUND: Natural history studies of untreated HIV infection are useful for clinicians, public health experts and policymakers to improve and monitor care, plan services and control, and to model the epidemic. Several natural history studies on homosexual men and intravenous drug users have been published from developed countries. A few studies have emerged on heterosexual populations from Africa. With an emerging epidemic, a similar study was required in India. This study was designed to determine the progression of HIV disease in a prevalent cohort of adult HIV-seropositive patients. METHODS: A prevalent cohort of 1009 patients comprising 488 asymptomatic HIV-seropositive persons, 259 with AIDS-related complex (ARC), and 262 with acquired immunodeficiency syndrome (AIDS) were recruited for the study at Sir J.J. Hospital, Mumbai. A case-control study was conducted to determine the correlation of clinical features and other factors with disease progression. Disease progression was determined from the asymptomatic stage to that of ARC and AIDS using time series analysis. The incubation period from HIV to AIDS was also determined, using Weibull curves. RESULTS: The median incubation periods for progression were: HIV to AIDS-7.9 years and ARC to AIDS--1.9 years. The median survival after developing AIDS was 19.2 months. A comparison of progressors and non-progressors revealed that disease progression correlated with clinical features such as chronic fever (OR 5.6), persistent generalized lymphadenopathy (OR 4.7), persistent cough for >1 month (OR 3.5), chronic diarrhoea (OR 3.3), oral candidiasis (OR 3.2), >10% loss of body weight within 1 month (OR 2.9), incident tuberculosis (OR 2.8) and herpes zoster (OR 2.5). The annual incidence of active clinical tuberculosis was 86/1503 person-years (5.7/ 100 person-years), the median time to occurrence of active tuberculosis was 21.6 months and the annual incidence of mortality was 96/2009 person-years (4.8/100 person-years, 95% CI 3.4, 6.2). CONCLUSION: Progression to AIDS and death was faster among the heterosexual cohort in Mumbai than that reported for homosexual men and haemophiliacs in the USA and Europe. Strategies need to be developed to prevent the occurrence of tuberculosis among HIV-infected patients because that would help to reduce the morbidity and mortality. This is the first large study from the Indian subcontinent of a longitudinal follow up of HIV-infected persons. The findings will be useful for advocacy and assessing the impact of antiretroviral therapy (ART) in India.Item Pathobiology of fungal infections of the central nervous system with special reference to the Indian scenario.(2007-07-09) Shankar, S K; Mahadevan, A; Sundaram, C; Sarkar, Chitra; Chacko, Geeta; Lanjewar, D N; Santosh, Vani; Yasha, T C; Radhakrishnan, V VUbiquitously present fungi in the environment find a nidus in the human body and adopt its metabolic machinery to be in symbiosis or become pathogenic. Immunocompromised states like human immunodeficiency virus (HIV) / acquired immunodeficiency syndrome (AIDS), systemic neoplasia and organ transplantation have enhanced the frequency of fungal infections. High-risk behavior, IV drug abuse and air travel have led to the emergence of new fungal infections hitherto geographically localized. The pathology in the central nervous system (CNS) is dictated largely by the size of the fungus - the yeast forms, by virtue of their small size enter the microcirculation to cause meningitis and microabscesses, while hyphal forms invade the vasculature to manifest as large pale or hemorrhagic infarcts. The growth kinetics of fungi, the antigenic character of the capsule. the proteases secreted by the mycelial forms and the biochemical milieu in the host also determine clinical manifestations. A hospital-based analysis of the available information from India suggests that in the non-HIV patient population, hyphal forms like Aspergillosis and Zygomycosis are the most common pathogens, while yeast forms like Cryptococcus and Candida are the prime pathogens in cases of HIV/AIDS, the altered macrophage function acting in synergy with suppressed cell-mediated immunity. In Northeastern states, systemic infection by Penicillium marneffei is reported in association with HIV though CNS involvement is not recorded. Although fungal infections of the CNS are reported from various hospitals in India, studies are limited by non-availability of relevant microbiological studies and the reported prevalence data is biased by the surgical practices, availability of postmortem and microbiology and laboratory support. Detailed clinical and mycological investigations related to the interaction between the fungus and host environment is a fertile area of research to understand the basic pathogenetic mechanisms.Item Pathology of the heart in acquired immunodeficiency syndrome.(1998-05-01) Lanjewar, D N; Katdare, G A; Jain, P P; Hira, S KThe spectrum of cardiac lesions in patients with acquired immunodeficiency syndrome in India is not described. To determine the extent of involvement of the heart with this disease, an autopsy study of 52 subjects having acquired immunodeficiency syndrome was carried out. Multiple sections were obtained from different anatomical parts of each heart. Forty-eight of the 52 hearts showed subtle microscopic changes, the most common being myocardial atrophy (48 cases), lymphocytic pericarditis (38 cases), fibrinous pericarditis (1 case), pericardial fibrosis (1 case), lymphocytic myocarditis (29 cases) and myocardial fibrosis (7 cases). Cryptococcosis of the heart was noticed in two cases, while in one case toxoplasmic myocarditis was identified. In only one case clinical presentation of cardiac involvement (pericardial effusion) was noted, which indicates that in spite of the presence of significant pathology in the heart, overt cardiac manifestations are infrequently seen in patients with acquired immunodeficiency syndrome.Item Perinatally acquired AIDS.(1993-04-01) Khanna, S A; Lanjewar, D N; Samdani, P G; Shinde, A BItem Pneumocystis carnii pneumonia in AIDS--an autopsy report.(1999-07-22) Lanjewar, D N; Nambiar, A; Anand, M; Jain, P PPneumocystis carinii pneumonia (PCP), the most common presenting manifestation in patients with AIDS from western countries, holds the distinction for being the first opportunistic infection that was associated with AIDS. There is marked paucity of clinically diagnosed and pathologically confirmed cases of PCP in India. This case represents the first complete autopsy report of pneumocystis carinii pneumonia inpatient with AIDS from our country. A high index of clinical suspicion and microscopic confirmation is needed to avert mortality due to PCP in patients with AIDS.Item Primary Osteosarcoma of the Breast.(2012-06) Badge, S A; Lanjewar, D N; Gosavi, A V; Ramteerthkar, N A; Kulkarni, M PPrimary osteosarcoma of the breast is an extremely rare and aggressive tumor representing 12.5% of mammary sarcomas. It is associated with early recurrence and hematogenous rather than lymphatic spread, most commonly to the lungs. We report a case of 55 year old lady with gradually increasing painless lump measuring 7 × 6 cm in upper outer quadrant of left breast of 2 months duration. FNAC smears revealed pleomorphic spindle cells admixed with osteoid and chondroid material. A differential diagnosis of metaplastic carcinoma and malignant phyllodes tumor was offered. Histopathology of the modified radical mastectomy specimen showed predominantly osteosarcomatous areas. Epithelial component was not seen even after extensive sampling of the tumor. On immunohistochemistry, vimentin, S100 and CD68 were positive while AE1/AE3, CAM5.2, ER, PR, Her2-neu and desmin were negative confirming a diagnosis of osteosarcoma. Primary osteosarcoma of breast must be differentiated from metaplastic carcinoma and malignant phyllodes tumor because of different biological behaviour and treatment approach. Immunohistochemistry plays a pivotal role in the diagnosis of this tumor.Item Prostatic tuberculosis and AIDS.(1994-07-01) Lanjewar, D N; Maheshwari, M BTuberculosis of the prostate is rare and is thought to be either due to haematogenous dissemination or secondary to renal infection. We describe, possibly for the first time, two male patients with the acquired immunodeficiency syndrome who had tuberculous abscesses in the prostate discovered at post-mortem examination. Only one of them had mild urinary symptoms and neither had evidence of urogenital tuberculosis before death. We suggest that in a patient with acquired immunodeficiency syndrome tuberculous infection of the prostate should be sought by microscopic examination of the urine, semen and prostatic fluid obtained after massage.Item Recurrent Kimura's disease: excellent response to cyclosporine.(2006-02-24) Shenoy, V V; Joshi, S R; Kotwal, V S; Shedge, R T; Ramraje, N N; Lanjewar, D NKimura's disease is a chronic inflammatory disorder involving the skin, subcutaneous tissues and lymph nodes, predominantly in the head and neck region. Though surgery, intralesional or systemic steroids or radiation therapy have been the mainstay of treatment recurrence is a common problem. On the basis of occasional case report of Kimura's disease responding to cyclosporine, we attempted oral cyclosporine in our patient with dramatic improvement.Item Renal lesions associated with AIDS--an autopsy study.(1999-01-27) Lanjewar, D N; Ansari, M A; Shetty, C R; Maheshwari, M B; Jain, PKidneys from 55 cases (20 with HIV infection and 35 with AIDS) were studied by routine Haematoxylin and Eosin stains and special stains (PAS, PASM GMS, ZN, Mucicarmine and Congo red) to evaluate, glomerular, interstitial and vascular pathology. Twenty-four of the 35 (68.6%) cases of AIDS showed infective aetiology which included 17 cases (48.5%) of tuberculosis, 5 cases (14.4%) of fungal infection (3 cryptococcus neoformans and 2 candida species) and 2 cases (5.7%) of CMV infection. Other lesions noted were amyloidosis and tubular calcinosis. HIV associated nephropathy (HIVAN) was not detected in any of the cases. Intravenous drug abuse was not a risk factor in our cases which probably explains the absence of HIV associated nephropathy in the present study.Item Right atrial appendage thrombus with atrial infarct in a case of thyrotoxicosis: An autopsy report.(2010-07) Lanjewar, D N; Ramraje, Sushma; Lanjewar, Sonali DCardiac function has long been known to be altered in patients with thyrotoxicosis and atrial fibrillation occurs in patients with hyperthyroidism. In addition to its disabling symptoms, atrial fibrillation is a strong risk factor for systemic embolism, especially with regard to cerebral circulation. A right atrial appendage thrombus formation in atrial fibrillation is a rare phenomenon. In this report, we describe a case of a 30-year-old female, who suffered from hyperthyroidism and subsequently developed atrial fibrillation and a right atrial appendage thrombus with infarction of right atrial appendage.
