Syphilis is a sexually transmitted infection caused by Treponema pallidum. The primary stage of the disease manifests as a chancre. Balanoposthitis as a presenting feature of primary syphilis is a very rare presentation. A 26-year-old male presented with asymptomatic erythematous plaques involving the glans and prepuce after unprotected intercourse with a known female. Routine investigations, serology, and dark field examination were normal. Fontana-Masson stain revealed spirochetes and a diagnosis of syphilitic balanitis of Follmann was entertained. This rare presentation accounts for only 0.3%-0.5% of cases of primary syphilis and hence is highlighted in this case report.

Malignant melanoma is predominantly a skin disease but in rare instances it may occur at other sites. A vaginal melanoma is a rare clinical entity and the round cell type is an uncommon variant. Although the present case was clinically diagnosed as a urethral caruncle, on histopathological examination and immunostaining it was diagnosed as a round cell pigmented malignant melanoma. The patient refused radical surgery and was given a full course radiotherapy treatment but died a year later. Malignant vaginal melanoma carries a very poor prognosis even when lesion is localised at the time of presentation. The five-year survival rate ranges from 10-20% with the prognosis being influenced by tumour size. A tumour size ≥3cm has a poor prognosis. Age, mitotic count, stage, and location of the lesion do not influence survival rates.
