Porocarcinoma is a rare type of skin cancer that develops from the intraepidermal ductal part of eccrine sweat glands. It can arise de novo or from poroma ground with high potential for locoregional metastatic spread, morbidity, and mortality. It mostly occurs in elderly patients.

Eccrine porocarcinoma (EPC) is an extremely rare, adnexal carcinoma that represents less than 0.01% of all cutaneous malignancies. An aggressive tumour with a high recurrence rate, it has a tendency to metastasise to regional lymph nodes. Once metastasis has occurred, mortality rate increases to 75%-80% and thus survival is dependent on adequate and timely resection of the lesion. EPCs are frequently missed as a differential diagnosis due to their rarity and non-specific appearance, which can lead to serious consequences for patients. Consequently, EPCs are an important diagnosis for clinicians to be aware of and consider when evaluating cutaneous lesions. We present a case of EPC of the knee, which was initially misdiagnosed as a benign lesion on magnetic resonance imaging (MRI). We discuss the use of MRI in aiding assessment of EPCs.

Acquired digital fibrokeratoma (ADF) is rare in clinical practice and is easily misdiagnosed. Herein, 5 cases of patients (3 males and 2 females) with ADF are reported. The mean age at onset was 42.6 years, and the mean disease duration was 3 years. Four patients had ADF on the hands, and 1 patient had ADF on the foot. The clinical manifestations were all solitary, skin-colored papules, with a firm texture and smooth surface, protruding from the skin surface. In 3 patients, ADF manifested as columnar protrusions, and in 2 patients, ADF manifested as dome-shaped protrusions. For all 5 patients, the diameters of the lesions were <1 cm. Clinically, all 5 patients were misdiagnosed (ie, eccrine poroma (EP), common warts, rudimentary polydactyly, pyogenic granuloma (PG), and acral fibroma). All cases of ADF were confirmed by histopathology. The histopathological manifestations of ADF were as follows: finger-like protrusions on the skin surface; collagen fiber bundles running vertically to the epidermis seen in the dermis; and thick red-stained collagen fibers connected with the normal dermal connective tissue below. All 5 patients underwent surgical resection; the distance between the incision margin and the edge of the tumor was 2-3 mm, and the surgical depth was the deep dermis. No recurrence was observed in more than half a year of follow-up after surgery.

An eccrine poroma (EP) is a benign adnexal tumor that typically presents as a single lesion. Eccrine poromatosis defined as multiple EPs is an uncommon presentation. A 54-year-old male had undergone operation for stomach cancer 10 years prior and insisted that he had also taken adjuvant chemotherapy. The patient presented with six reddish papules and nodules scattered on the trunk and extremities for 3 years. The histopathologic findings from all six lesions were consistent with EP. No local recurrence was observed after complete removal through punch biopsies. We report a rare case of eccrine poromatosis in the patient with gastric cancer, suspected of being caused by chemotherapy.
