Eccrine porocarcinoma : a case with local recurrence, regional lymph node and extensive cutaneous metastases

الملخص EN

A 64-year old male patient presented to the dermatology clinic with few weeks history of multiple papulonodular skin lesions over the left thigh, associated with limb edema and palpable lymph nodes in the left inguinal region.

The patient had a skin lesion over his left ankle, excised 7 months earlier and the pathology report came with the diagnosis of squamous cell carcinoma.

A biopsy was taken from one of the thigh lesions, and histopathological examination revealed metastatic porocarcinoma into the overlying skin with lymphatic infiltration.

A histopathological review of the first biopsy showed a porocarcinoma, apparently completely excised.

In conclusion, this case presentation highlights the tendency of porocarcinoma for local recurrence and metastasis to skin and lymph nodes.
