RESUMO
Colloid carcinoma (pure mucinous carcinoma) is an uncommon variant of breast carcinoma with distinctive cytological and histological features. These tumors are characterised by islands of tumor cells floating in a sea of abundant extracellular mucin. We present the cytology of two cases of colloid carcinoma occurring in 80-year-old and 45-year-old females. The fine-needle aspiration cytology helps to subcategorize the tumor type, thereby enhancing the knowledge about the distinctive cytological features of special and uncommon variants of breast carcinoma, their course and prognosis. A distinctive micropapillary variant of pure mucinous carcinoma which is rarely described, is represented in one of the cases. Also we report, here, colloid carcinoma in a female of reproductive age, a relatively uncommon occurrence.
RESUMO
Molluscum contagiosum is a cutaneous viral infection presenting as multiple, umbilicated papules and vesicles. The cytology of molluscum contagiosum in an 11-year-old boy, which presented atypically as a solitary nodule over the right cheek, mimicking a skin adnexal tumor is reported here. Fine needle aspiration cytology plays a vital role in establishing the correct diagnosis of clinically unsuspected cases, and hence, the proper management of such lesions. The cytology of molluscum contagiosum is characterized by the presence of numerous large intracytoplasmic basophilic bodies that push the host nucleus to the periphery, giving a signet ring appearance to the superficial epidermal cells.
