Item Cutaneous angiomyolipoma.(2009-04-01) Singh, Kulwant; Pai, Radha Ramachandra; Kini, Hema; Kini, Ullal AnandCutaneous angiomyolipomas are rare. We report a case in a 45-year-old male with a well circumscribed lesion located on the chin. This lesion, probably hamartomatous in nature, differs from renal angiomyolipoma in terms of nonassociation with tuberous sclerosis, circumscription, and male predominance. Another characteristic feature is the absence of epithelioid cells. Differential diagnosis includes angiolipoma, angioleiomyoma, hemangioma, and myolipoma. It is distinguished from the abovementioned entities by the presence of a combination of thick-walled blood vessels, smooth muscle, and fat.Item Cytomorphological features of combined myxoid and round cell liposarcoma--a case report.(2005-07-10) Chowdhury, Nilotpal; Pai, Radha Ramachandra; Lobo, Flora DorothyFine needle aspiration cytology plays an important role in the preoperative assessment of soft tissue neoplasms. In a 40-year-old man presenting with a large soft tissue mass in the posterior aspect of thigh a diagnosis of myxoid liposarcoma was suggested on FNAC. Scrape smears of the excised mass showed an additional finding of round cell component. Histopathology confirmed combined myxoid and round cell liposarcoma (grade 2), which behaves aggressively when compared to pure myxoid liposarcoma.Item Leiomyosarcoma of the urinary bladder: a case report.(2004-01-09) Gopalakrishnan, Kishore; Pai, Radha Ramachandra; Kini, Hema; Prabhu, G G LaxmanA case of leiomyosarcoma of the urinary bladder occurring in a middle aged lady with immunohistochemical confirmation is presented for its rarity with emphasis on grading of smooth muscle neoplasms of the urinary bladder.Item Myoepithelioma of the Lateral Border of Tongue - A Rare Site of Occurrence and Dilemma of Diagnosis(Akshantala Enterprises Private Limited, 2020-11) Karikal, Arvind; Kudthadka, Arathi; Shetty, Tripthi Prakash; Pai, Radha RamachandraItem Salivary duct carcinoma of the parotid gland: the cytohistological features.(2007-10-01) Pai, Radha Ramachandra; Alwar, Vanamala; Rao, Vatsala Srinivas; Somayaji, VasudevaA 62-year-old man presented with rapidly growing tumour in the right parotid region with associated pain and facial nerve palsy. Based on the fine needle aspiration cytology report of high-grade mucoepidermoid carcinoma, parotidectomy was performed which showed features of salivary duct carcinoma. The smears were reviewed to identify the potential pitfalls in the cytological diagnosis of salivary duct carcinoma.Item Sarcomatoid renal cell carcinoma with osteosarcomatous differentiation--a case report.(2004-10-22) Handoo, Anil; Pai, Radha Ramachandra; Rao, Vatsala Srinivas; Sanjeeva, Venkatesh BA rare case of sarcomatoid renal cell carcinoma (RCC) with predominantly osteosarcomatous differentiation occurring in a 36-year-old male is reported. Immunohistochemistry excluded the possibility of primary osteosarcoma of the kidney.Item Sclerosing stromal tumour of the ovary--a clinicopathologic spectrum.(2005-07-10) Pai, Radha Ramachandra; Shaktawat, Sameer Singh; Khadilkar, Urmila Niranjan; Lobo, Flora Dorothy; Rao, Vatsala Srinivas; Philipose, RebaMajority of the Sclerosing stromal tumours of the ovary documented in the literature are single case reports. We report a series of 4 cases. Among the 4 cases encountered the mean age at presentation was 22.2 years. The clinical presentation varied from asymptomatic mass per abdomen (2 cases), menorrhagia (1 case) and amenorrhoea (1 case). The tumour was unilateral in all the cases with an average size of 10 cms. Grossly the appearances varied from a solid, partly cystic, edematous tumour (2 cases) to solid,firm tumour with yellow flecks (1 case) to unilocular cystic tumour (1 case). Microscopically, the tumour was characterized by cellular pseudolobules composed of a disorderly admixture of collagen-producing fibroblasts and lipid rich lutein cells with shrunken nuclei. In one case the lutein cells had a robust appearance with abundant cytoplasm and vesicular nuclei. The pseudolobules were very vascular and separated by hypocellular dense to oedematous fibrous tissue. Frozen section demonstrated fat in luteinized cells in 3 cases.Item T-cell rich B-cell lymphoma--a case report.(2003-07-18) Pai, Radha Ramachandra; Khadilkar, Urmila Niranjan; Pai, Muktha Ramesh; Dinesh, MT-Cell-Rich B-Cell lymphoma (TCRBCL) is a recently described variant of diffuse large B-cell lymphoma characterized by a predominance of reactive T-cells and a minority of neoplastic large cells which may resemble the Reed-Sternberg cell or its variants. TCRBCL is a notorious mimicker of both lymphocyte predominance Hodgkin's disease (LPHD) and peripheral T-cell lymphoma (PTCL). Immunohistochemistry is mandatory for a definitive diagnosis. We report a case of TCRBCL which was mistaken for HD both on fine needle aspiration cytology and histopathology due to the presence of RS like cells. Immunohistochemistry resolved the diagnostic dilemma.
