“…3 There is a malignant variant, the porocarcinoma, which may be a primary tumor, but generally results from the malignant transformation of EP. 7 Approximately 8% of cases present as multiple lesions, named poromatosis. 3 The lesions tend to be asymptomatic and, in roughly 50% of cases, are located in the plantar region.…”

Poromas are uncommon benign neoplasms originating from the terminal ductal portion of the sweat glands, mainly characterized by skin-colored or pink pa pules or nodules, usually on the extremities. Due to their rarity, the pigmented form clinical hypothesis is hardly ever suggested and psychopathology is fundamental. We report a case of pigmented eccrine poroma in the right palmer area, a location considered atypical. We stress the importance of dermoscopy as a method for diagnosis of poromas, especially in the differential diagnosis with other pigmented nodular-popular lesions.

“…2,7,8, As also reported in the Mulinari-Brenner and cols review, the lesions varied between 1.2 x 2.0 and 4 x 5 cm. 9 In the case presented, the lesion was extensive, affecting the entire anterior thorax, a less common region, seen in 24% of the cases described in the literature. 10 The most affected locations, in 44% of cases, are the lower limbs, with 11% for the leg and 10% for the feet.…”

Eccrine porocarcinoma is a rare, malignant neoplasm of eccrine sweat glands. It often occurs in elderly people, mean age of 67.5 years. The clinical features are variable and their localization is not related to sweat-gland concentration, occurring mainly on the feet and legs. Disease diagnosis and treatment should be as early as possible in order to avoid tumor aggressiveness that occurs in 20% of the cases. The authors present a case of extensive porocarcinoma on the thorax of a 71-year-old male patient.. Keywords: Acrospiroma; Carcinoma; Eccrine glands; Sweat gland neoplasms Resumo: O porocarcinoma écrino é uma neoplasia maligna, rara, das glândulas sudoríparas écrinas e, com maior frequência, acomete os indivíduos idosos, com idade média de 67,5 anos. Apresenta manifestações clínicas variadas e sua localização não se correlaciona com a concentração das glândulas sudoríparas, ocorrendo, principalmente, nos pés e pernas. O seu diagnóstico e tratamento devem ser precoces para evitar a agressividade do tumor, que ocorre em 20% dos casos. Os autores relatam o caso de um porocarcinoma extenso no tórax, em paciente do sexo masculino, de 71 anos.

“…There is no clear consensus about the optimal surgical margins for porocarcinoma. Surgical margins between 3 mm and 10 mm have been reported to be effective [11,12]. In a review of 1968 patients with different subtypes of adnexal carcinomas, it was suggested that the surgical margins should be at least 2 cm after wide local excision.…”

Adjuvant radiotherapy in the management of porocarcinoma with lymphatic micrometastasis

Background. Porocarcinoma is a rare skin tumor originating from dermal sweat glands. Surgical procedures are the first choice of treatment, but the role of adjuvant therapies, such as chemotherapy and radiotherapy (RT), is not clear. In this case report and review of the literature, we aimed to present a patient who underwent adjuvant RT for the diagnosis of porocarcinoma with lymphatic micrometastasis and a review of the current literature.Case summary. A 61-year-old male was admitted to the dermatology department for a nodular lesion on the left knee skin. An excisional biopsy was performed, and the pathology result was reported as porocarcinoma.The closest surgical margin of the tumor was 0.2 cm. In the inguinal sentinel lymph node sampling, two of the three removed lymph nodes had micrometastases. Then, adjuvant RT was applied to the left inguinofemoral lymphatics and primary tumor bed. No recurrence was observed in the patient with a follow-up period of 24 months.No acute or late toxicity was observed including lymphedema, subcutaneous fibrosis, or stiffness of the knee joint.Conclusions. Although adjuvant RT is not a routinely recommended treatment, it can be applied to increase local and regional control in patients with high-risk factors for recurrence or with lymph node metastases. There is a great need for clinical studies clarifying the role of RT, but for now, all patients should undergo multidisciplinary evaluation when a decision on adjuvant therapies is made.
