A Case of Steatocystoma Multiplex Treated with Combination of Needle Aspiration and Trichloracetic Acid / 대한피부과학회지

Steatocystoma multiplex is a clinical condition characterized by numerous dermal cysts that have their origin in the pilosebaceous duct, which appear and grow at puberty. The cystic nodules range from 3 mm to 3 cm in size, and they are soft and freely movable. Although there are numerous reports of different treatment methods, the long-term management of steatocystoma multiplex remains to be difficult. We, herein, report on a case of 23-year-old man with steatocystoma multiplex on the buttock. He was successfully treated with dot peeling of 100% trichloracetic acid after aspiration of the oily contents without any complications, such as atrophy, scarring and skin necrosis. We report the combination therapy of needle aspiration and trichloroacetic acid peeling as new therapeutic modality for multiple steatocystoma multiplex.

A Case of Acrodermatitis Enteropathica Localized on the Hands and Feet with a Normal Serum Zinc Level

Acrodermatitis enteropathica is classified as a congenital autosomal recessive type and an acquired transient type. This disease manifests as acral and periorificial dermatitis, alopecia, intractable diarrhea, and failure to thrive. Whereas the autosomal hereditary type is caused by malabsorption of zinc in the intestine, the acquired type is caused by low nutritional support or decreased peripheral release of zinc from blood. We experienced a case of a 5-month old, breast feeding, full-term female presenting with only acral bullous dermatitis without diarrhea, periorificial dermatitis and an abnormal serum zinc level.

Late-Onset Eccrine Angiomatous Hamartoma Associated with a Ganglion Cyst on the Sole of the Foot

Eccrine angiomatous hamartoma (EAH) is a benign, uncommon, combined vascular and eccrine malformation. Most cases of this disorder have been single or multiple nodules or plaques that appear red, yellow, blue, violaceous, or skin colored. EAH may be congenital or appear later in childhood; it rarely arises during puberty or adulthood. A 52-year-old female patient visited our department for tender subcutaneous cystic tumor on the right sole with a one month history. Histopathologic examination confirmed EAH. During excisional biopsy procedure, mucinous discharges were observed which were histopathologically diagnosed as ganglion.

A Case of Lichen Planus Pigmentosus-inversus in a Korean Patient

Lichen planus pigmentosus-inversus is a rare variant of lichen planus pigmentosus. The eruption of lichen planus pigmentosus-inversus occurs mainly in the flexural regions and presents with brownish macules and patches. Here we describe the case of a 31-year-old Korean woman who presented with hyperpigmented lesions over her antecubital and popliteal area and groin. Physical examination revealed multiple brownish macules and patches on the intertriginous area without pruritis, and histologic findings showed a regressive pattern of lichen planus. These clinical and histological findings were consistent with a diagnosis of lichen planus pigmentosus-inversus.

A Herpes Simplex Virus Infection Secondary to Acupuncture and Cupping

Acupuncture and cupping have a public reputation as being safe even though these practices can lead to complications such as trauma or infection. We report here on a case of herpes simplex virus (HSV) infection secondary to acupuncture and cupping in a 56-year-old woman. The patient, who had a history of acupuncture and cupping on her left forearm for treating her myalgia, developed painful papules. Histologically, the biopsy specimen showed characteristic ballooning degeneration and inclusion bodies in the epidermis and mid-dermis. These clinical and histological findings were consistent with the diagnosis of HSV infection.

Rippled-pattern Sebaceoma / 대한피부과학회지

Sebaceoma is a benign neoplasm with sebaceous differentiation, and this is characterized by dermal aggregations of basaloid, immature sebaceous cells and sebaceous duct-like structures. Recently, some cases of sebaceoma that presented as a rippled-pattern resembling the palisading of nuclei of verocay bodies have been reported in the English literature. However, there has been no such report in the Korean dermatologic literature. We report here on a case of rippled-pattern sebaceoma that developed in a 78-year-old Korean man.

A Case of Recurrent Superficial Acral Fibromyxoma

Superficial acral fibromyxoma (SAFM) is a rare myxoid tumor that was first described in 2001. The presence of a very slow growing solitary tender mass in the subungual area is the typical clinical feature at presentation. Histopathologically, SAFM is composed of stellate cells in a myxocollagenous matrix with a poorly circumscribed margin. This tumor is thought to be benign, but its natural course is not fully understood. We describe a 15-year-old patient with recurrent SAFM and discuss the proper treatment and follow up.

Secondary Cicatricial Alopecia due to Morphea Involved in Frontoparietal Area through the Eyebrow / 대한피부과학회지

Morphea, a subclass of localized scleroderma, is a connective tissue disorder limited to the skin and subcutaneous tissue. We report herein a case of secondary cicatricial alopecia due to morphea, which showed very unusual site and clinical manifestations. A 24-year-old woman presented to the department of dermatology with a solitary skin-colored patch on the frontoparietal area through the eyebrow. The histopathologic findings showed hydrophic changes of the basal cells in the epidermis. In addition, there were broadened, compact, eosinophilic collagen fibers and perifollicular lymphocytic infiltration with loss of elastic fibers and adnexal structures in the entire dermis. On the basis of clinical and pathological findings, she was diagnosed with secondary cicatricial alopecia due to morphea on the frontoparietal area through the eyebrow.

Dominant Dystrophic Epidermolysis Bullosa / 대한피부과학회지

Dystrophic epidermolysis bullosa is a rare, chronic non-inflammatory bullous disease with a hereditary pattern of occurrence, and this disease easily produces bullae that heal with scarring and milium formation. A 13-month-old female baby was brought to the department of dermatology with multiple variable sized bullae and erythematous to dark brownish patches and crusts on both her feet. The histopathologic findings showed subepidermal non-inflammatory blisters and the electron microscopic findings showed vacuolization of the sublamina densa and broken anchoring fibrils. On the basis of the clinical and microscopic findings, she was diagnosed as having dominant dystrophic epidermolysis bullosa. We report here on a case of dominant dystrophic epidermolysis bullosa with the clinical, histological and electron microscopic findings, as well as the family history of the patient.

An Open Label, Multi-center Clinical Trial of Topical 5% Minoxidil Solution for the Treatment of Male Androgenetic Alopecia (A Phase IV Study) / 대한피부과학회지

BACKGROUND: Topical 5% minoxidil solution stimulates new hair growth and it helps stop the loss of hair on individuals with androgenetic alopecia (AGA). OBJECTIVE: We wanted to assess the efficacy and safety of topical 5% minoxidil solution for treating Korean men with AGA. METHODS: This was a 24-week, open label, clinical trial that was conducted at 14 university dermatologic centers nationwide throughout South Korea as a multicenter study of the Korean Hair Research Society. The eligible subjects for this study were 18- to 65 year-old men with androgenetic alopecia, as defined by the Norwood scale as type III vertex, IV and IVA. A total of 175 men (20~62 years old) with AGA applied topical 5% minoxidil solution twice daily. Efficacy was evaluated by 1) the total hair count per 1 cm2 and 2) the mean hair diameter and 3) the patient assessment and 4) the investigator assessment of the change in scalp coverage and the benefit of treatment. RESULTS: At week 24 as compared with baseline, there was a statistically significant increase in the total hair counts and the mean hair diameter (p<.0001). Topical 5% minoxidil solution helped improve the investigator and patient assessments. The topical 5% minoxidil solution was well tolerated over a 24-week period. CONCLUSION: We believe that topical 5% minoxidil solution is a safe and effective drug for Korean men with AGA.

A Case of Relapsing Polychondritis Associated with Scleritis / 대한피부과학회지

Relapsing polychondritis is a rare rheumatologic disorder most commonly presenting as recurring episodes of inflammation in cartilaginous tissues. Auricular chondritis with red ears resembling cellulitisis the most common clinical manifestation. Other manifestations include arthritis, nasal chondritis, and ocular, pulmonary, and cardiovascular disease. Here we report the case of a 54-year-old female patient with relapsing polychondritis and associated scleritis. On histologic examination, the auricle, including cartilaginous tissues, showed loss of the normal basophilia of cartilage and perichondrial infiltration of inflammatory cells. The patient was treated with systemic steroids. Symptoms in both auricles were reduced, scleritis developed, and ocular symptoms were waning.

A Case of Trichilemmal Cyst on the Abdomen / 대한피부과학회지

Trichilemmal cyst is a benign tumor that originates from the external root sheath. It usually occurs on the scalp, but rarely on the face, neck and trunk. A 41-year-old man presented with a skin-colored non-tender subcutaneous nodule on his abdomen. The histopathologic findings of the lesion showed a well demarcated cystic mass with trichilemmal keratinization in the dermis. It was diagnosed as a trichilemmal cyst and then it was totally excised. We report here on a case of trichilemmal cyst on the abdomen, which is known to be an unusual site for this type of lesion.

A Case of Angiolymphoid Hyperplasia with Eosinophilia / 대한피부과학회지

Angiolymphoid hyperplasia with eosinophilia (ALHE) usually presents as pink to red-brown, dermal papules or nodules on the head and neck, especially around the ears and on the scalp. ALHE also occurs in the mouth, trunk, and extremities, penis and vulva. It can be painful or itchy and is known to be partly (20%) associated with peripheral blood eosinophilia. Histopathological findings show proliferation of blood vessels with plump endothelial cells and perivascular infiltration of numerous lymphocytes and eosinophils. We reported a 30-year-old female patient who had mild pruritic erythematous papules on the scalp that histopathologically showed features of ALHE. She was successfully treated with an intralesional injection of triamcinolone acetonide.

Intratumoral Fat in Neurofibroma and Coexistence of Eccrine Hidrocystoma

We report a case of intratumoral fat in neurofibroma and coexistance of eccrine hidrocystoma on the occipital area of the scalp for one year duration. There are several diseases showing fatty change histopathologically. Among them, few cases of neurofibroma showing fatty change had been reported. The mechanism of fatty change is unclear, but several hypotheses are proposed. Here we report a case of neurofibroma showing fatty change and coexistence of eccrine hidrocystoma, and discuss the pathomechanism of fatty change and its relationship with disease.
