RATIONALE
Eccrine poroma, a benign cutaneous neoplasm originating from the intraepidermal portion of the eccrine sweat duct, is relatively common in clinical practice. Nevertheless, the 1 presenting as spindle-shaped plaque is extremely rare and easily misdiagnosed as seborrheic keratosis or other dermatoses. Thus, the current study demonstrates a case of eccrine poroma with unique clinical manifestation.
PATIENTS CONCERNS
A 47-year-old man presented with a spindle-shaped plaque on his left sole for 6 years.
DIAGNOSES
Based on the clinical and histopathological manifestations, diagnosis of eccrine poroma was established.
INTERVENTIONS
Surgical excision under local anesthesia was performed.
OUTCOMES
No recurrence or malignant transformation occurred within 6-month follow-up.
LESSONS
Eccrine poroma typically presents as a dome-shaped nodule on palm or sole. But this case reminded us the lesion presenting as a spindle-shaped plaque on sole can not rule out the possibility of eccrine poroma.

Secondary neoplasms in nevus sebaceous can develop during adolescence and adulthood. Trichoblastoma and syringocystadenoma papilliferum are the most common benign neoplasms, but poroma is rarely reported. A 28-year-old female presented with an asymptomatic mass on the scalp. She has had a hairless lesion on the scalp since birth. A soft mass developed on that lesion four years prior. Physical examination revealed a localized 1 cm×2.5 cm-sized brownish, verrucous-surfaced plaque with a 1 cm×1 cm-sized pedunculated erythematous tumor on the scalp. We performed skin biopsy on both the plaque and tumor lesions. The histopathological findings demonstrated the plaque lesion consistent with nevus sebaceous and the tumor lesion consistent with eccrine poroma. Surgical mass excision was performed. The patient was eventually diagnosed with eccrine poroma arising within nevus sebaceous. To the best of our knowledge, there are only six reported cases on poroma arising within nevus sebaceous. Although rarely documented in the literature, it should be considered as a secondary neoplasm within nevus sebaceous.

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.

BACKGROUND
Eccrine porocarcinoma (EPC) is a rare malignant cutaneous adnexal tumor. Other than several scattered case reports, no comprehensive review on EPC has been conducted in Korea.
OBJECTIVE
To clinicopathologically review all EPC cases from our institutions as well as those reported in Korea.
METHODS
Medical records and histopathological slides of EPC cases in the skin biopsy registries of our institutions were retrospectively reviewed. Additionally, EPC cases reported in Korea before June 2019 were retrieved by searching the PubMed, KoMCI, KoreaMed, and KMbase databases.
RESULTS
Nine EPC cases from our institutions were included in the study. In addition, 27 reports of 28 patients with EPC were reported in Korea. A total of 37 patients with EPC were identified, consisting of 19 males (male:female ratio, 1.06:1; mean age at diagnosis, 65.6 years). The most common site of primary tumor was the head and neck (29.7%). Wide excision was the most common (78.4%) treatment method. Initial metastasis work-up imaging studies were performed in 18 patients (48.6%), and metastasis was confirmed in eight patients (21.6%).
CONCLUSION
EPC is a rare cutaneous carcinoma in Korea. EPC usually affects elderly patients, with no sexual predilection. Due to possible metastasis, careful diagnosis and appropriate metastasis work-ups are warranted in EPC.
