Polymorphous Cutaneous Sarcoidosis With Excellent Response to Minocycline.

Sarcoidosis is notorious for producing a wide variety of skin lesions, which are categorized as either specific or nonspecific. The specific lesions include primary morphologies ranging from micropapules to subcutaneous nodules. Nonspecific skin lesions include associated conditions like erythema nodosum, calcinosis cutis, and prurigo. It is not uncommon for a patient to have a combination of specific and nonspecific lesions. In contrast, it is exceedingly rare for one patient to have multiple specific sarcoidal lesions. When present, the term "polymorphous cutaneous sarcoidosis" has been used. We present the case of a patient who presented with three specific cutaneous morphologies of sarcoidosis: papular sarcoid, Darier-Roussy subcutaneous sarcoidosis, and lupus pernio. After only two months of oral minocycline, our patient demonstrated remarkable improvement with near-complete resolution of the cutaneous lesions. In addition to describing the rare polymorphous presentation, this case also highlights the challenge of relating lesion type to overall prognosis when multiple morphologies are present.

Postinflammatory hypopigmentation: a comprehensive review of treatments.

Postinflammatory hypopigmentation is an acquired form of hypopigmentation that occurs secondary to an exogenous or endogenous insult to the skin. It can occur in all skin phototypes but is more visually apparent in skin of color. Due in part to greater attention given to its counterpart, postinflammatory hyperpigmentation, there is a dearth of literature describing this entity and treatment options remain limited. This review provides a comprehensive update on the pathogenesis, diagnostic evaluation and treatment of postinflammatory hypopigmentation, with a focus on newly reported treatment modalities.

Autoimmune skin disease among dermatology outpatients in Botswana: a retrospective review.

BACKGROUND: There is a paucity of data describing autoimmune skin diseases in sub-Saharan Africa and in HIV positive cohorts. We describe the incidence of autoimmune skin diseases in public dermatology clinics in Botswana. METHODS: New patient records from public dermatology clinics were reviewed retrospectively for the period of September 2008 to December 2015. New diagnoses of cutaneous lupus erythematosus, systemic lupus erythematosus (SLE) with cutaneous involvement, dermatomyositis, systemic sclerosis, lichen sclerosus, bullous pemphigoid, pemphigus foliaceus, pemphigus vulgaris, and pemphigus vegetans were identified. Demographic data were recorded, and incidence was determined. RESULTS: A total of 262 patients were diagnosed with autoimmune skin disease (4% of all new patients) with an incidence rate of 28.8 (per 1,000,000). Cutaneous lupus was the most common diagnosis with discoid lupus occurring most frequently (12.6). The incidence of systemic sclerosis (2.2), morphea (1.6), lichen sclerosus (1.5), SLE with cutaneous involvement (1.3) and dermatomyositis (1.2) was relatively lower. Bullous pemphigoid was the most common bullous disease (3.8). Pemphigus foliaceus (0.9), pemphigus vulgaris (0.6), and pemphigus vegetans (0.2) were observed at a lower rate. At least 19.8% of these patients were also HIV positive. CONCLUSIONS: The incidence of autoimmune skin diseases in Botswana is lower compared to other published studies in other geographic areas, which may be reflective of a younger population, barriers to access, genetic differences, and a lack of comparative studies in sub-Saharan Africa. The hygiene hypothesis and helminth infections may also contribute to these differences. Further studies are needed to understand these disorders in this region.

Teledermatology as a Means to Provide Multispecialty Care: A Case of Global Specialty Collaboration.

Telemedicine can serve as a platform for specialty collaboration and potentially address the lack of specialized and subspecialized care globally. In this article we present a case in which the use of teledermatology facilitated global collaboration between multiple specialists and subspecialists, resulting in high-quality care of a child from a remote area of Botswana. We present the lessons learned and factors that should be considered when engaging in global specialty collaboration, especially between developed and developing countries. We also discuss the potential limitations of telemedicine when used within a global context. With these considerations in mind, global specialty collaboration facilitated by telemedicine can provide a potential solution to the lack of access to specialized and subspecialized care.
