Late-onset nevus of Ota.

We report a patient with a type IB nevus of Ota whose lesion did not appear until she was thirty years old. To our knowledge, this represents the oldest age of a patient at clinical onset of nevus of Ota. The diagnosis, implications, and treatment of nevus of Ota are reviewed.

Papular acne scars. A common cutaneous finding.

One hundred thirty-three patients were examined for the presence of a cutaneous eruption consisting of small, asymptomatic, hypopigmented, follicular papules on the upper part of the trunk. The papules were present in 57% of patients who had a history of acne vulgaris and in 9% of patients who denied ever having had acne. Biopsy specimens from five patients revealed circumscribed, perifollicular or parafollicular lesions in which both elastic and collagen fibers were attenuated in comparison with those in normal adjacent dermis. These changes are consistent with scar. We conclude that the papules are a scarring process secondary to acne vulgaris and propose calling the lesions papular acne scars. They appear closely related to or identical with changes previously termed perifollicular elastolysis, postacne anetoderma-like scars, and papular elastorrhexis.

Eruptive disseminated lobular capillary hemangioma (pyogenic granuloma).

A 43-year-old man reported a 2-month history of numerous widespread vascular lesions that had developed suddenly on his scalp, trunk, and extremities. The lesions were 2 to 6 mm in diameter, firm, dark red papules that bled easily with minor trauma. Histopathologic examination of four lesions revealed lobular capillary hemangioma, also known as pyogenic granuloma. Treated lesions did not recur after surgical excision or electrocauterization. Five months after the onset of the eruption, no new lesions were developing, and some were resolving spontaneously after bleeding. Eruptive, disseminated lobular capillary hemangioma is a rare, self-limited cutaneous disorder that occurs in otherwise healthy persons.

Acne vulgaris.

Acne vulgaris is a disease of the pilosebaceous unit that affects nearly all persons to some degree during the teenage years. It is a disease that should be treated because of the anxiety and disfigurement it causes in the affected patient. Acne therapy is directed against the three probable pathogenic processes in acne: (1) abnormal keratinization of the sebaceous follicle, (2) excessive production of sebum, and (3) proliferation of bacteria in the follicle. Superficial acne consisting of comedones and small papulopustules will frequently respond to topical therapy such as retinoic acid, benzoyl peroxide, and topical antibiotics. Deeper lesions require systemic antibiotics of which tetracycline is the drug of choice. Severe, recalcitrant cystic acne usually responds well to the oral retinoid, isotretinoin. The severe teratogenic effects of isotretinoin on a developing fetus make this a risky drug to prescribe for women with childbearing potential. In such cases the greatest precautions should be taken to avoid pregnancy during a course of isotretinoin. Such precautions include pregnancy testing, contraceptive counseling, and the use of at least two effective forms of birth control in sexually active women.

Congenital erosive and vesicular dermatosis healing with reticulated supple scarring: report of three new cases and review of the literature.

Congenital erosive and vesicular dermatosis healing with reticulated, supple scarring is a rare disease with seven reported cases in the literature. This congenital cutaneous defect of unknown etiology presents with patchy or generalized erosions and vesicles at birth that heal with striking reticulated scarring. We report three new cases of this rare disease and review the literature.
