Fine needle aspiration cytology of chondroblastoma: A report of two cases with brief review of pitfalls.

Chondroblastoma is a rare, giant cell-rich, benign neoplasm of bone. Since the past few decades fine needle aspiration cytology (FNAC) has gained momentum in preoperative diagnosis of bone lesions. At cytology, other giant cell-rich tumors and tumorlike lesions such as aneurysmal bone cyst (ABC), giant cell tumor, and chondromyxoid fibroma fall under the differential diagnosis of chondroblastoma.

Rippled pattern extraocular sebaceous carcinoma: a rare case report with brief review of literature.

Sebaceous carcinoma (SC) is a highly aggressive malignant adnexal tumor of sebaceous gland origin, accounting for less than 1% of cutaneous. Extraocular sebaceous carcinomas are more aggressive than their ocular counterpart with a predilection for the skin of head and neck, trunk, salivary glands and extremities in decreasing order of frequency. Rippled effect literally means "gradually spreading effect".

An association between hypoplastic myelodysplastic syndrome and T-prolymphocytic leukaemia.

Myelodysplastic syndrome (MDS) represents one of the most challenging health-related problems in the elderly, characterized by dysplastic morphology in the bone marrow in association with ineffective hematopoiesis. Hypoplastic MDS (h-MDS) accounts for 12-17% of all patients with MDS and has yet to be shown to alter the disease course or prognosis. The concept that T-cell-mediated autoimmunity contributes to bone marrow failure in MDS has been widely accepted due to hematologic improvement after immunosuppressive therapy.
