Syringoma*

Syringoma is the most common type of benign intraepidermal eccrine sweat gland tumor in Korea, and is usually found in women in their forties. It presents mostly as a localized lesion, preferring the lower eyelid, cheek, or forehead, and rarely invades the vulval area, and in the case of children, vulvar invasion is even more rare. Tranilast is an antihistamine used for atopic dermatitis and asthma, and has recently been used for the treatment of keloid. A few previous studies have reported both localized and generalized forms of syringoma being effectively resolved with tranilast. Herein, we report a rare and interesting case of milium-like syringoma, which manifested on the vulval area of 10-year old girl that was successfully treated with tranilast.

Syringomas are common benign neoplasms that are derived from the intradermal eccrine duct and frequently manifest in adult females as 1~3-mm flesh-colored papules on the face, especially on the lower eyelid. There are two hypotheses about their pathogenesis: ductal obstruction by keratin plugs and reactive eccrine proliferation following an inflammatory condition. The patient was a 66-year-old man with multiple erythematous papules and nodules on both periorbital areas after 7-day sorafenib (Nexavar®) treatment. A skin biopsy of the Rt. periorbital lesion revealed multiple cysts and tadpole-shaped tubular structures in the dermal layer. Inflammatory cell infiltration was seen throughout the dermis. Based on the clinical features and histological findings, we diagnosed the patient with syringoma-like eccrine duct proliferation. The indications for and use of Sorafenib have increased recently. Although sorafenib-associated cutaneous side effects have increased, no cases of syringoma-like eccrine duct proliferation have been reported to date. Here we report a case of sorafenib-induced syringoma-like eccrine duct proliferation in a patient with hepatocellular carcinoma.

BACKGROUND: Protease-activated receptor 2 (PAR-2) participates in various biological activities, including the regulation of epidermal barrier homeostasis, inflammation, pain perception, and melanosome transfer in the skin. OBJECTIVE: To evaluate the basic physiological role of PAR-2 in skin. METHODS: We investigated PAR-2 expression in human epidermis, skin tumors, and cultured epidermal cells using western blot and immunohistochemical analysis. Additionally, we examined the effect of the PAR-2 agonist, SLIGRL-NH2, on cultured keratinocytes. RESULTS: Strong PAR-2 immunoreactivity was observed in the granular layer of normal human skin and the acrosyringium of the eccrine sweat glands. In contrast, weak PAR-2 immunoreactivity was seen in the granular layer of callused skin and in the duct and gland cells of the eccrine sweat glands. Interestingly, PAR-2 immunoreactivity was very weak or absent in the tumor cells of squamous cell carcinoma (SCC) and syringoma. PAR-2 was detected in primary keratinocytes and SV-40T-transformed human epidermal keratinocytes (SV-HEKs), an immortalized keratinocyte cell line, but not in SCC12 cells. SV-HEKs that were fully differentiated following calcium treatment displayed higher PAR-2 expression than undifferentiated SV-HEKs. Treatment of cultured SV-HEKs with PAR-2 agonist increased loricrin and filaggrin expression, a terminal differentiation marker. CONCLUSION: Our data suggest that PAR-2 is associated with terminal differentiation of epidermis and eccrine sweat glands.

Microcystic adnexal carcinoma is a rare type of tumor, with about 300 cases reported globally. Due to its similar histology with other tumors, it is occasionally misdiagnosed as desmoplastic trichoepithelioma, basal cell carcinoma, syringoma, and so on. We present a patient with a mass on the perioral area who was preoperatively diagnosed with trichoepithelioma. Microcystic adnexal carcinoma was diagnosed after excisional biopsy and a wide excision. Defects were reconstructed with a mucosal advancement flap. There was no recurrence and there were no significant complications during the 18-month follow-up period. Because superficial punch biopsy has limitations in width and depth, surgeons should always consider the possibility of malignancy of a mass even if a biopsy shows a benign result.

Scrotal calcinosis is a relatively common tumor of the male genitalia but there is controversy in the literature regarding its pathogenesis. The authors of many case reports debate whether the lesions are truly idiopathic or if they arise from other conditions. Only few cases of scrotal calcinosis have been proven to have an eccrine origin so far. Herein, we report a case of scrotal calcinosis originating from a milium-like syringoma in a male Korean patient.
