“…It is regarded as the rare malignant counterpart of eccrine poroma, a benign tumor of the intraepidermal eccrine sweat gland duct [2]. Porocarcinoma is commonly found in older age group and usually located in the lower extremities (more than 50%), rarely may occur on scalp, face, ear, upper extremities, trunk and abdomen [1,3]. In the scalp, it is commonly seen in occipital region [4,5].…”

Malignant tumors occurring in the scalp are uncommon. When scalp swellings are asymptomatic, small in size or covered by hair usually they are neglected by patients. This may lead to a potential risk of delay in detection and treatment which may cause poorer results. Here we are presenting the case of scalp swelling of unknown duration and pre-operative investigation had showed benign lesion and was managed accordingly but post operatively it was found malignant and metastasized rapidly and become incurable. So any unusual, ulcerated/pigmented lesion of the scalp we must consider the possibility of a tumor and reconstruction with flap should be done after confirmation of the diagnosis.

Background The aim of the study is to analyze potential prognostic factors and to evaluate therapy strategies regarding clinical outcome in patients with eccrine porocarcinoma (EPC) of the head and neck. Methods One hundred and sixteen EPC cases from ninety studies and four authors' EPC cases were included in the meta‐analysis. Results At an average follow up of 20.48 months, the 3‐year overall survival and regional recurrence rate were 70.3% and 19.0%, respectively. Patients without surgical treatment had a significantly worse 3‐year overall survival. Mohs microscopic surgery led to significantly less occurrence of regional recurrences compared to wide excision. An ulcerating lesion, high mitotic activity, and lymphovascular invasion were significant prognostic factors. Conclusion Surgical resection is the cornerstone in the therapy of EPC and represents the therapeutic modality that offers the best chance of disease‐free survival. Due to the high probability of recurrence, close follow‐ups are strongly recommended.
