Dermoscopy of penile sclerosing granuloma

Abstract

Penile sclerosing granuloma is a foreign body reaction to the injection of material, usually for genital augmentation purposes. Patients commonly deny having had or performed these procedures on themselves, and diagnosis can be challenging. We describe the case of a 62-year-old man with a 10-year history of a growth on the penile shaft. Dermoscopic examination showed an orange background with shiny white structures, suggesting a granulomatous pathology. Guided biopsies confirmed a sclerosing lipogranuloma. The patient admitted to having self-injected motor oil. For the first time, we report the dermoscopic description of sclerosing granuloma, which will improve clinical diagnostic precision and guide biopsies. We also contribute the first description of a dermoscopic rainbow pattern in a granulomatous disorder; this could be due to a physical phenomenon called ‘dichroism’.

Iatrogenic lipogranuloma of the penis

“…More recently, Navarrete et al . 9 reported a similar case. A 62-year-old male injected oil subcutaneously into his penis 10 years ago, which resulted in significant penile thickening.…”

Choose your biopsy site wisely — the utility of dermoscopy in the diagnosis of Bowen’s disease of the face

“…Dermoscopy has already been reported as a useful tool for the selection of a biopsy site and therefore facilitation of the diagnosis of melanocytic lesions [7,8], cicatricial alopecia [9][10][11][12][13], extramammary Paget's disease [14], melanonychia [15] and penile sclerosing granuloma [16]. Dermoscopy may not only aid selection of the biopsy site but also guide nail abrasion for mycological samples in case of onychomycosis [17].…”
