​Dermatology - Genital Lentiginoses
Genital lentiginoses are harmless pigmented growths that develop in adulthood.

The coloration of the macules on the vulva (labia minora), penis (glans, shaft), and perianal areas is typically tan, brown, or deep blue-black. These macules, which are generally variegated and measure 5 to 15 millimeters, occur in clusters and remain unchanged in size for several years.

The diagnosis is made by a clinical examination and can be verified by using dermoscopy or by performing a biopsy of the affected area. The differential diagnosis encompasses melanoma in situ, fixed drug reaction, blue nevus, and squamous cell cancer.
Lesions of considerable size that are difficult to remove should be monitored using photography; any areas that exhibit notable changes should undergo biopsy.
