A 7-year-old girl presented with solitary, asymptomatic, nodule near right angle of mouth for 8 months. The lesion started as a small papule and increased in size over time. The child was otherwise healthy. On examination, single erythematous nodule measuring 1 cm, and of soft to firm consistency, was seen near the right angle of mouth. The top of the lesion was eroded and covered with crust. Rest of the muco-cutaneous examination was unremarkable (Fig. 1). During examination, whitish paste like material was expressed during palpation. Giemsa stain of the material showed faint bluish cytoplasmic inclusions (Fig. 2). The lesion was removed by shave excision and was sent for histopathology. The histopathology findings were acanthosis and eosionphilic cytoplasmic inclusions, confirming the diagnosis of molluscum contagiosum. Family members were examined and classical molluscum contagiosum lesions were noted in brother (left temple region) and mother (abdomen). After shave excision, oral and topical antibiotic was advised for 7 days; the lesion resolved completely in 2 weeks, without any sequale.

Solitary molluscum contagiosum poses a diagnostic challenge and is confused with keratoacanthoma (firm lesion with central keratin material) and granuloma pyogenicum (soft friable lesion with history of bleeding on minor trauma or spontaneously). Cytopathology can be helpful in rapid diagnosis of such lesions.
