1/10. larva migrans within scalp sebaceous gland.

    A case of larva migrans or serpiginous linear dermatitis on the scalp of a teenager is reported. An ancylostomid larva was found within a sebaceous gland acinus. The unusual skin site for larva migrans as well as the penetration through the sebaceous gland are highlighted. The probable mechanism by which the parasite reached the skin adnexa is discussed.

2/10. Confocal imaging of sebaceous gland hyperplasia in vivo to assess efficacy and mechanism of pulsed dye laser treatment.

    BACKGROUND AND OBJECTIVE: This case demonstrates, for the first time, the use of in vivo confocal imaging to assess the efficacy of laser treatment of a skin lesion with a vascular component. STUDY DESIGN/PATIENT AND METHOD: A patient with lesions of sebaceous gland hyperplasia was histologically imaged in vivo before and after treatment with a 585 nm pulse dye laser (PDL) by using a near-infrared, confocal reflectance microscope. Hyperplastic sebaceous ducts and sebaceous glands were seen with high resolution in vivo. Prominent dermal vasculature was viewed as well as its selective targeting by PDL. CONCLUSION: Our results confirm the previously reported successful treatment of sebaceous gland hyperplasia with the 585 nm PDL. ( info)

3/10. Familial nevoid sebaceous gland hyperplasia affecting three generations of a family.

    Familial sebaceous gland hyperplasia is a benign entity with onset at puberty and a tendency to worsen with age. It is characterized by a nevoid symmetric pattern in the sebaceous areas of the face sparing the orbital, perinasal, preauricular and perioral areas showing prominent follicular openings and interfollicular dermal yellowish or white prominent skin. Usually, the face is affected, with the neck, column and thorax affected in a milder pattern. We describe a family with familial nevoid sebaceous gland hyperplasia in three consecutive generations. All the patients were successfully treated with oral isotretinoin. The pedigree suggests autosomal dominant inheritance with incomplete penetrance. ( info)

4/10. Closure of a scalp defect.

    In repairing cutaneous defects, the facial plastic and reconstructive surgeon is faced with many specialized areas of tissue. Reconstruction of thin eyelid skin and thick, sebaceous nasal skin requires different methods. The unique characteristics of the scalp make it one of the greatest repair challenges in the head and neck region, sometimes requiring multiple different reconstructive techniques for the same defect.

5/10. Basal cell carcinoma originating from a nevus sebaceus on the scalp of a 7-year-old boy.

    Basal cell carcinoma (BCC) occurs rarely in children and is most often associated with an underlying condition that predisposes patients to the development of malignancy. There have been numerous reports of BCC developing after puberty in nevus sebaceus; however, such occurrences have rarely been described in children. We report a 7-year-old boy with BCC forming in a nevus sebaceus. ( info)

6/10. Juxta-clavicular beaded lines in a kidney transplant patient receiving immunosuppressants.

    Juxta-clavicular beaded lines (JCBL) are unique malformations of sebaceous glands or a variant of sebaceous hyperplasia with characteristic clinical features (1, 2). We describe a patient with JCBL, who received immunosuppressants following kidney transplantation. To our knowledge, our patient is the first case of JCBL in a kidney transplant recipient. ( info)

7/10. Zileuton, an oral 5-lipoxygenase inhibitor, directly reduces sebum production.

    BACKGROUND: Zileuton, a 5-lipoxygenase inhibitor, reduces the number of inflammatory lesions in moderate acne and inhibits the synthesis of sebaceous lipids. OBJECTIVE: To detect whether zileuton directly reduces sebum synthesis. methods: A 40-year-old female with mild disseminated sebaceous gland hyperplasia and seborrhea was treated with zileuton 4 x 600 mg/day over 2 weeks, was followed-up for 6 weeks after discontinuation of zileuton and was re-treated with low-dose isotretinoin 10 mg/2nd day over 5 weeks. Casual skin surface lipids and sebum synthesis were determined. RESULTS: Under treatment with zileuton increased casual skin surface lipids were normalized and synthesis of facial sebum was decreased. Six weeks after discontinuation of treatment casual skin surface lipids were increased again and synthesis of sebum returned to baseline. Subsequent low-dose isotretinoin treatment led to similar changes of casual skin surface lipids and sebum synthesis with zileuton already after 2 weeks. CONCLUSION: Zileuton directly inhibits sebum synthesis in a transient manner with a potency similar to low-dose isotretinoin at least in our patient. ( info)

8/10. Keratin 17 mutation in pachyonychia congenita type 2 patient with early onset steatocystoma multiplex and Hutchinson-like tooth deformity.

    pachyonychia congenita type 2 (PC-2) is an autosomal dominant disorder characterized by hypertrophic nail dystrophy, focal keratoderma, multiple pilosebaceous cysts, and other features of ectodermal dysplasia. It has been demonstrated that PC-2 is caused by mutations in the keratin 17 and keratin 6b genes. In this report, we describe a missense mutation in the keratin 17 gene, M88T, in a Korean patient whose phenotype included early onset steatocystoma multiplex and Hutchinson-like tooth deformities along with other typical features of PC-2 such as hypertrophic nails, natal teeth and follicular hyperkeratosis.

9/10. An unusual hamartoma of the folliculosebaceous-apocrine unit: a case report.

    hamartoma is a neoplasm-like lesion composed of an abnormal mixture of tissues native to the area. We report on an unusual example of a hamartomatous lesion that showed an abnormal mixture of elements of the folliculosebaceous-apocrine unit and arrector pili muscle. A 13-year-old female presented with two nodules situated 2 cm apart on the lower leg that were present since birth. The patient reported some enlargement and slight pain of the otherwise asymptomatic lesions during 2 years, before they were surgically removed. The patient obviously had no skin problems afterwards; her 12-year follow-up was significant for leucopenia and nephrolithiasis. The biopsies from both lesions looked identical. Each lesion was biphasic, i.e. composed of a predominant mesenchymal component and epithelial elements. The mesenchymal part resembled a leiomyoma, or in minor areas, the constituting cells had a myofibroblastic appearance. Encased within the mesenchymal component were large infundibulocystic structures and plentiful grouped and scattered roundish solid epithelial nodules, duct-like, glandular, and tubular elements. Some of the epithelial structures were reminiscent of those seen in tubular apocrine adenoma; others resembled syringomatous elements. We interpreted this unusual lesion as a hamartoma of the folliculosebaceous-apocrine unit. ( info)

10/10. Idiopathic disseminated comedones in a child.

    An 11-year-old girl had an uncountable number of hyperkeratotic comedo-like lesions on her shoulders, arms, buttocks, and thighs, present for 5 years. Depressed scars, cysts, and small purulent nodules were observed in involved areas. Her 6-year-old brother does not have similar lesions. Other members of her family were not available for examination. light microscopy showed dilated elongated infundibula filled with corneocytes and arranged in a lamellated pattern. A peri-infundibular inflammatory infiltrate was present. ( info)
