Giant soft tissue chondromas (STCs) of the wrist are seldom encountered in clinical practice. Precise diagnosis of benign STC may pose diagnostic difficulties on clinical and radiological findings alone. We encountered a slowly growing soft tissue neoplasm in the radial aspect of the wrist joint of the right hand in a 52-year-old male, masquerading as a calcified hematoma, as suggested by magnetic resonance imaging. On cytohistopathological examination, it turned out to be a rare giant STC. The variable cellularity, in conjunction with cellular immaturity and atypia, could mislead one to a malignant pathological interpretation. Diagnosis is based on both radiological and cytohistological evaluation, which is indispensable for determining the tumor type. The detailed clinical, radiological, cytomorphological, and immune-histopathological study was carried out, which has prompted us to report this case along with a review of the literature.

Fine-needle aspirations (FNA) have played a crucial role in the diagnosis and follow-up of malignancies including sarcomas. However, relatively low specifi city in the classifi cation of sarcoma is the main limitation of FNA. Epithelioid sarcoma is a rare tumor of soft tissues. Very few individual case reports describing cytological features of epithelioid sarcoma have been documented in the literature. Here, we describe cytological features of epithelioid sarcoma with immunocytohistological correlation. [ABSTRACT FROM AUTHOR]

Invasive apocrine carcinomas of the breast are rare. Fine needle aspiration cytology (FNAC) has been increasingly used as a primary screening tool for breast lumps, with high level of sensitivity and specificity. Preoperatively, apocrine carcinoma needs to be distinguished from benign apocrine lesions and other eosinophilic and granular cell tumors. We report a rare case of invasive apocrine carcinoma in a 70-year-old female presenting with a breast lump and no axillary lymphadenopathy. FNAC was advised which yielded moderately cellular smears composed of loosely cohesive clusters of large, polygonal cells with centrally located pleomorphic, vesicular nucleus with prominent nucleoli and abundant, basophilic and granular cytoplasm. Based on above cytomorphological findings, diagnosis of apocrine carcinoma was offered. The patient then underwent right modified radical mastectomy with axillary clearance. Based on histomorphology and panel of immunohistochemical (IHC) markers the diagnosis was confirmed. Although apocrine/oncocytic cytomorphology is seen in few types of breast neoplasms, high index of suspicion and subsequent IHC study clinches the diagnosis. [ABSTRACT FROM AUTHOR]
