Eruptive vellus hair cyst in a patient with pachyonychia congenita.

Pachyonychia congenita is characterized by symmetrical nail dystrophy, palmoplantar keratoderma, oral leukokeratosis, and follicular hyperkeratosis. In addition to these features, multiple cutaneous cysts of various kinds have been described. We report a case of pachyonychia congenita associated with eruptive vellus hair cyst.     

Comparative treatment of multiple vellus hair cysts with the 2940 nm Er:YAG and 1540 nm Er:Glass laser

Abstract

Eruptive vellus hair cysts occur sporadically, hereditarily or in association with other diseases due to developmental anomalies of vellus hair follicles. Here, we report on a 41-year-old male with multiple vellus hair cysts of the forehead, who was successfully treated three times with a non-ablative, non-fractional 1540 nm Er:Glass laser on one side of his face, and with an ablative non-fractional 2940 nm Er:YAG laser on the other side, at intervals of 6–12 weeks. Over the whole treatment period of about 9 months, we could observe a marked reduction in the total number of cysts. The bigger and painful inflammatory cysts were reduced significantly. There was a slight tendency for better clinical outcome in the area in which the Er:YAG laser had been used. Clinical and histopathological findings, pathogenesis and treatment options are discussed with a review of the literature.     

Two Pilosebaceous Cysts with Apocrine Hidrocystoma in One Biopsy Site: A Spectrum of the Same Disease Process?

A 28-year-old woman presented with multiple, asymptomatic, erythematous to bluish papules located on the chest. Histopathologically, three round, well defined cystic structures were seen on the upper and lower dermis. The first cyst was milia, the second was apocrine hidrocystoma and the other, largest cyst was an eruptive vellus hair cyst (EVHC). A diagnosis of multiple pilosebaceous cysts combined with apocrine hidrocystoma was made. Since the milia and EVHC originate from the pilosebaceous unit, and the apocrine duct opens to the pilosebaceous orifice, we suggest that they can occur simultaneously in the same unit.     

Eruptive vellus hair cyst and epidermoid cyst in a patient with pachyonychia congenita

We report the first case of pachyonychia congenita (PC) associated with both eruptive vellus hair cyst (EVHC) and epidermoid cyst. The patient is a 12-year-old Japanese girl who presented with two natal teeth at birth. She had thickening and discoloration of the fingernails and toenails, plantar hyperkeratosis, palmar-plantar hyperhidrosis and multiple cutaneous cysts. Histologic examination revealed EVHC and epidermoid cyst.     

Steatocystoma multiplex and eruptive vellus hair cyst

Background of study Steatocystoma multiplex (SM) and eruptive vellus hair cyst (EVHC). are both entities with similar clinical features, hut with important histological differences. In the last few years, several authors have reported examples of both cysts with mixed historical features, and have proposed the idea that the two conditions are related.
Subjects We report here 3 cases, histological features of SM. EVHC, and the other presenting cysts with mixed histological findings.
Conclusions The different histological findings in the cases reported support the idea that SM and EVHC are extremes of a spectrum     

Tinea of vellus hair: an indication for systemic antifungal therapy

Background Topical antifungal treatment is indicated in tinea of glabrous skin, except in cases of extensive, multiple or recurrent lesions, or immunocompromised patients. However, in daily practice there are cases resistant to topical treatment despite these indications. Parasitism of the hair could be the cause behind the majority of isolated lesions of ringworm of hairless skin with a poor outcome with topical antifungal treatment. Objectives To present a prospective observational study of 13 cases of tinea of glabrous skin with topical antifungal resistance during the period 2007–2009. Methods Cases were analysed from a clinical, mycological and therapeutic standpoint. Results The mean age was 7 years. Eight (62%) patients reported prior contact with an animal and 10 (77%) patients had received topical corticosteroids before visiting the dermatologist. Excoriation was observed in eight (62%) patients, and follicular micropustules were seen in 11 (85%). In all patients, some short thin hairs fell easily on to the slide during the skin scraping. In all patients all the few vellus hairs identified in direct examination were affected. All identified species were zoophilic or geophilic. All cases resolved after oral antifungal treatment. Conclusions In tinea of glabrous skin with low response to topical antifungal treatment we must rule out tinea of the vellus hair. Infection by nonanthropophilic dermatophytes, previous corticosteroid therapy and excoriation might be predisposing factors. Parasitism of the vellus hair, observed by direct microscopy, should be another criterion for establishing systemic treatment from the onset, as is the case in tinea capitis.
