Giant solitary trichoepithelioma (GST) is a rare trichogenic tumor, which may present as a pigmented lesion. An 80-year-old man was diagnosed to have giant solitary trichoepithelioma on fine-needle aspiration cytology. The cytological findings represented the histological features. The recognition of GST is important because of its close resemblance to basal cell carcinoma and other skin adnexal tumors – clinically, cytologically and histologically.

Intracranial meningiomas are not often aspirated unless they erode the skull and present as swelling in the head and neck region. We describe the cytologic findings of fine needle aspiration cytology in a clear cell variant of intracranial meningioma presenting with swelling in the left parietal region of the scalp in a 45-year-old woman. The diagnosis was confirmed by histopathology. Clear cell meningioma is characterized by patternless sheets of clear polygonal cells. Clear cell meningioma is a rare distinctive cytological subtype of meningioma with high recurrence rate and increased mortality, which necessitate frequent follow-up after surgical excision. The recognition of clear cell meningiomas is important here and should be distinguished from other clear cell lesions of the scalp. If clear cell epithelial neoplasm is encountered on fine needle aspiration, it is reasonably possible to provide at least a differential diagnosis of meningioma based upon the focal whorls, sparce vascularity on low magnification, along with the presence of pseudoinclusion and inconspicuous nucleoli at high magnification.

Neoplastic urothelium has the capacity to demonstrate enormous plasticity. A variety of unusual morphological variants of urothelial carcinoma have been described. Micropapillary variant of urothelial carcinoma is a rare and recently described bladder tumor, associated with poor prognosis. We present the cytological features of micropapillary urothelial carcinoma in a 65-year-old man with bladder mass. The cytological features include tightly cohesive clusters of micropapillary component admixed with urothelial carcinoma. Histopathological sections showed small nests of tumor cells residing within the lacunae. Establishing a diagnosis of micropapillary urothelial carcinoma indicates a high-grade and high-stage tumor with poor outcome, requiring an aggressive therapy. It is thus important for the cytopathologist to recognise micropapillary variant of urothelial carcinoma, for early and better management of patients with bladder tumor.

Cranial fasciitis is a rare variant of nodular fasciitis, which is seen exclusively in infants and childhood, mainly in the head and neck region. It is considered as non-neoplastic lesion similar to nodular fasciitis.A 5 months old male child presented with a rapidly growing swelling in the forehead, since three months. No other complaints. CT scan revealed erosion of the outer table of cranium and radiologically diagnosed as Dermoid cyst. The swelling was excised. Histologically it showed more cellular areas, forming storiform pattern with myxoid areas and bony metaplastic change. Few osteoclastic giant cells seen and was diagnosed as cranial fasciitis of childhood. The cranial fasciitis should be considered as one of the differential diagnosis or differentiated from fibromatosis that tend to recur locally, unlike nonrecurring behavior of these lesions in childhood.
