The mystic thyroid nodule: A cytologist's confront.

Metastatic thyroid carcinoma is clinically silent and found only at autopsy in most instances. Renal cell carcinoma (RCC) is the most common and constitutes 56% of all secondary malignancies. However, preoperative distinction between primary and secondary thyroid neoplasms is often challenging.

Dermatopathic lymphadenitis in HIV.

Dermatopathic lymphadenitis is a rare entity described in patients with Human immunodeficiency virus infection. Here we present a case of dermatopathic lymphadenitis in a 50-year-old female who was HIV positive and did not have any obvious skin lesions. Fine needle aspiration cytology of the lymphnode showed a lymphoproliferative lesion and a subsequent biopsy showed atypical lymphoid proliferation showing prominent T-zone.

Fine-needle aspiration cytology findings in human immunodeficiency virus lymphadenopathy.

Thirty-six human immunodeficiency virus (HIV)-positive patients with lymphadenopathy were subjected to fine-needle aspiration cytology (FNAC) over a period of 2 years. The maximum number of cases was reported in the age group of 21 to 30 years. Majority of the patients were males.
