Chromophobe renal cell carcinoma with rare distant metastasis.

Metastasis accounts for the most common tumor of the central nervous system (CNS) in adults. Renal cell carcinoma (RCC) is one of the common carcinoma showing brain metastasis, with a predilection for clear cell variant. Chromophobe RCC (ChRCC) in contrast to clear cell RCC shows far less common distant metastasis.

Microfilaria and Strongyloides larva diagnosed in cerebrospinal fluid and ascitic fluid, respectively: Approach to their morphology on cytology.

Filariasis and Strongyloidiasis are two endemic parasitic infections seen in any tropical country. Filariasis, commonly caused by Wuchereria bancrofti, Brugia malayi, and Brugia timori is seen often in peripheral blood and lymphoid tissue. But it can be isolated from wide variety of soft tissue sites in the body like soft tissue lumps, breast, thyroid, body fluids.

Liquid-based cytology of pigmented phaeohyphomycotic lesion of the palm masquerading as a metastatic tumor.

Phaeohyphomycosis is a chronic subcutaneous fungal infection caused by dematiaceous fungi, commonly involving the extremities, which present as single or multiple lesions mimicking a benign tumor. Fine-needle aspiration cytology (FNAC) is an easy method for the diagnosis of the lesion. Morphology of the fungus is characteristic with no difficulty for cytopathologist for identification; with a close differential diagnosis of Candida and Aspergillosis.

Cutaneous granular cell tumor clinically mimicking ectopic breast diagnosed on fine needle aspiration cytology.

Granular cell tumor (GCT) is a rare benign neoplasm of Schwannian origin which accounts of 0.5% of soft tissue tumors. Although the most common site for GCT is tongue, it can occur at any site.
