Cutaneous Endometriosis after Abdominal Myomectomy

Endometriosis is the aberrant presence of endometrial tissue outside the uterine cavity. We report a case of cutaneous endometriosis which developed on the scar of a uterine myomectomy in a 35-year-old female. The patient presented with a bean-sized, oval-shaped, erythematous nodule, which was located where a drain tube had been inserted. During her first visit to our clinic, she felt slight pain upon light touch to the lesion. She was not menstruating at this time. The lesion had been getting bigger and she reported that the pain was aggravated during menstruation. Diagnosis was confirmed by histopathologic examination, which showed multiple endometrial glands with decidualized stroma, and hemosiderin pigment. Many dermatologists are not familiar with cutaneous endometriosis. Therefore, we present this case as a good example which shows pathognomonic symptoms and characteristic histopathologic findings of cutaneous endometriosis.

Cutaneous Silicone Granuloma Treated with Oral Minocycline and Intralesional Injection of Triamcinolone Acetonide / 대한피부과학회지

Liquid silicone which is used for cosmetic enhancement can potentially induce a granulomatous reaction of variable severity. Treatment of silicone granuloma is challenging and often uncorrectable. We describe a case of adverse granulomatous inflammation after the injection of silicone. This was improved with oral minocycline and intralesional injection of triamcinolone acetonide.

A Case of Multiple Cutaneous Plexiform Schwannomas Accompanying Neurologic Deficits / 대한피부과학회지

Plexiform schwannoma is a rare variant of benign schwannoma characterized by a multinodular and plexiform growth pattern. Schwannomatosis is a recently recognized disorder, defined as multiple, pathologically-proven schwannoma without vestibular tumors, diagnostic of neurofibromatosis 2. Although plexiform schwannoma is usually solitary, multiple plexiform schwannomas do also occur as an isolated finding or in association with neurofibromatosis 2. We describe a 7-year-old girl who had multiple cutaneous plexiform schwannomas and neurologic deficits such as sensorineural hearing loss and amblyopia on her left side. Brain magnetic resonance imaging and ophthalmologic examination was negative for vestibular schwannoma and eye stigmata of neurofibromatosis 2. However, as there is a possibility that the patient may eventually develop additional cranial tumors such as meningiomas or vestibular schwannomas, we therefore recommend that she is periodically screened.

A Case of Squamous Papilloma in Oral Mucosa / 대한피부과학회지

Squamous papilloma is a commom benign lesion of the oral mucosa, but rarely encountered in dermatologic practice. Usually, oral squamous papilloma is a solitary peduculated lesion with verrucous surface, and known to be associated with human papilloma virus (HPV). We experienced a histologically confirmed case of oral squamous papilloma which occured in a 54-year-old man.
