Abstract

BACKGROUND: Eccrine poroma is a benign tumour of eccrine duct epithelium. The usual clinical presentation is nodular.

CASE REPORT: We present a 78-year-old man with a painful pendulating flesh-coloured malodorous plantar tumour. Differential diagnoses included telangiectatic granuloma, acrochordon, basal cell or squamous cell carcinoma, cylindroma, amelanotic melanoma, and verruca. Microbiological investigations identified numerous bacteria including Corynebacterium striatum, Streptococcus dysgalactiae, Staphylococcus aureus, Citrobacter koseri. We performed surgery since the tumour hampered his mobility. Histopathology revealed a well-circumscribed tumour composed of cuboidal cells with eosinophilic cytoplasm. Healing was unremarkable.

CONCLUSIONS: Pendulating plantar eccrine poroma is a rare clinical presentation of this benign adnexal tumour. Often asymptomatic, in some cases the tumour may become painful. Because of the bacterial colonisation, it could lead to deep soft tissue infections. Malignant transformation is possible. Surgical removal is the treatment of choice.
