A Case of Loose Anagen Hair Syndrome in a Southeast Asian Boy
We report the case of a 13-year-old Thai boy who presented with a single patch of hair thinning on the frontal scalp with excessive shedding, and the hairs did not grow long. Microscopic examination showed naked anagen bulbs with ruffling of the cuticle, which is compatible with loose anagen hair syndrome. To our knowledge, there is no reported case in Southeast Asian children.Case Rep Dermatol 2019;11:204 –208 (Source: Case Reports in Dermatology)

We describe the case of a 23-year-old Thai female who had a history of systemic lupus erythematosus with lupus nephritis type III and who developed widespread skin and nail infections caused byT. erinacei that were most likely transmitted from a hedgehog. Although the patient did not demonstrate a clinical improvement or mycological cure following systemic itraconazole and fluconazole treatment, she achieved clinical and mycological cures after terbinafine therapy. A drug susceptibility test should be performed in patients withT. erinacei infections to facilitate decision-making about antifungal therapy. Here, we are the f...

Mosquito Bite-Induced Localized NK/T-Cell Lymphoma Relapsed in a Patient with Complete Remission of Extranodal NK/T-Cell Lymphoma, Nasal Type
We report a rare case of localized NK/T-cell lymphoma following a mosquito bite after achieving complete response of extranodal NK/T-cell lymphoma, nasal type (ENKL). T cells and NK cells infected by Epstein-Barr virus (EBV) lead to NK/T-cell lymphoma, including ENKL. Lymphoma related to mosquito bites usually requires a prolonged treatment course, and the disease onset of hypersensitivity begins in early childhood. In the current case, the patient had no history of hypersensitivity to mosquito bites. We speculate that the latently EBV-infected NK/T cells in the blood were reactivated by mosquito gland antigens, expanded a...

Localized Hypertrichosis with Traumatic Panniculitis: A Case Report and Literature Review
Localized hypertrichosis with traumatic panniculitis is considered a rare condition. Previous articles have reported occurrence in females aged between 20 and 35 years. Possible mechanisms of trauma-induced localized hypertrichosis include hyperemia and angiogenesis induced by local inflammation, which can alter the hair growth cycle. The presence of inflammatory cells and lipomembranous changes on histopathology can support the diagnosis. We herein present a 35-year-old female patient with localized hypertrichosis following blunt trauma.Case Rep Dermatol 2019;11:180 –186 (Source: Case Reports in Dermatology)

Nail Lichen Planus in a Patient with Cogan Syndrome: Report of a Case and Discussion
Cogan syndrome and lichen planus represent two autoimmune disorders. Cogan syndrome is a very rare type of ANCA-negative vasculitis affecting the eyes and vestibulocochlear system. It has been associated with other autoimmune disorders, none of them showing any lichenoid inflammation. We herein report the first case of a patient that suffered from Cogan disease and developed isolated lichen planus on all nails a few years after the first diagnosis. The combination of two autoimmune disorders is not unusual and raises the question of common immunogenetic pathomechanisms.Case Rep Dermatol 2019;11:175 –179 (Source: Case...

Linear and Annular Lupus Panniculitis of the Scalp: Case Report with Emphasis on Trichoscopic Findings and Review of the Literature
Linear and annular lupus panniculitis of the scalp (LALPS) is a unique subset of lupus panniculitis, which results in non-scarring alopecia along the Blaschko line of the scalp in an otherwise healthy young patient.

Original Method to Repigment Achromic Laser Tattoo Removal Scars
Laser tattoo removal is expensive, painful, and time-consuming. Even with the use of the right laser equipment, it is often impossible to eliminate all pigments. Incomplete tattoo removal, one of the undesired effects of laser treatment, is widely disseminated in the media and accepted by most patients. However, few patients know that laser tattoo removal can cause permanent scars. Some patients who develop achromic scars can feel disappointed with the results of laser tattoo removal and take legal action against the physician responsible for the treatment.

Successful Treatment with Topical Diphenylcyclopropenone for Three Cases of Anogenital Warts in Children
Anogenital warts are caused by human papillomavirus types 6 and 11. They are rare in children, and treatment is difficult since conventional treatments are generally painful and require the patient to be anesthetized. Topical diphenylcyclopropenone (DPCP) is a contact immunotherapy used for treatments of recalcitrant warts and alopecia areata. We herein report 3 cases of anogenital warts in children successfully treated with topical DPCP. Our results suggest that topical DPCP may be a valuable option for the treatment of anogenital warts in children who have difficulty with painful destructive therapy.Case Rep Dermatol 201...

Hidradenitis Suppurativa is a Diagnosis to be Discussed
One of the values of case reports is that they foster communication between the involved parties. The cases included in this mini-review all underline different aspects of communication: between peers but also between physicians and patients. Few things, if any, can equal the concrete occasion to discuss empirical data. Among physicians, communication can not only create awareness but just as importantly provide solutions or suggest perspective to problems, while communication with patients is at the very core of medicine. These aspects are demonstrated in four cases dealing with the disease hidradenitis suppurativa.Case R...

Alopecia Diffusa while Using Interleukin-17 Inhibitors against Psoriasis Vulgaris
We report two cases of alopecia diffusa during the treatment of psoriasis vulgaris with interleukin (IL)-17 inhibitors. Psoriasis is one of the most common immune-mediated chronic skin diseases, strongly associated with IL-17A. Clinically, the monoclonal antibodies to IL-17A or its receptor, IL-17R, show a dramatic effect against psoriasis. Alopecia is also an IL-17-mediated autoimmune disease, and IL-17 inhibitors have been expected to be the gold standard for the treatment of alopecia; therefore, the complication of alopecia while using IL-17 may be regarded as an unexpected “paradoxical reaction.” T helper (...

Discrete Papular Lichen Myxedematosus and Scleromyxedema with Hypothyroidism: A Report of Two Cases
Scleromyxedema and lichen myxedematosus (LM) are rare disorders that fall along the spectrum of primary cutaneous mucinoses. Scleromyxedema is a systemic form that classically presents with generalized waxy papules, sclerodermoid eruption, and monoclonal gammopathy; LM is a localized form limited to the skin that classically presents with white, firm, waxy papules and lacks monoclonal gammopathy. According to diagnostic criteria established in 2001, the diagnosis of both conditions requires absence of thyroid disease. However, atypical cases that lack monoclonal gammopathy and that present with hypothyroidism have been rep...

The authors present a classic case of Churg-Strauss syndrome with an exuberant clinical picture in a 34-year-old woman. She showed the following diagnostic criteria: asthma, polyneuropathy, rhinopathy, marked eosinophilia, positive p-ANCA with a perinuclear pattern, and skin histopathology results suggestive of vasculitis with eosinophils. There was a good response to prednisone, dexamethasone pulse therapy, and cyclophosphamide.Case Rep Dermatol 2018;10:175 –181 (Source: Case Reports in Dermatology)
