A rare complication of follicular hair unit extraction: Kaposi's varicelliform eruption.

Follicular hair unit extraction (FUE) is becoming a popular type of hair transplantation recently. Kaposi's varicelliform eruption (KVE) is an uncommon skin emergency due to cutaneous dissemination of several types of viruses, most notably herpes virus, over the lesions of preexisting skin disorders. A 34-year-old man visited our dermatology outpatient clinic with a blistering, itchy and tender eruption on his head and body. He had undergone follicular FUE for androgenic alopecia 12 days previously, and 5 days after the procedure, umbilicated and/or hemorrhagic vesiculopustules appeared firstly on the occipital scalp skin where the hair units were taken. The lesions had rapidly spread over the upper chest and back. After the operation, he had taken oral methylprednisolone, amoxicillin clavulanate and had used fusidic acid ointment without any benefit. Bacterial culture of the pustules yielded no microorganism, while Tzanck smear from the vesicles revealed multinuclear giant cell groups. Based on a diagnosis of KVE, we treated the patient with oral valacyclovir hydrochloride 1000 mg 3 times a day for 14 days. Symptoms cleared rapidly, pustules and vesicles dried in a few days, and re-epithelialization of the eroded areas started at the end of the first week. The reported complications of FUE include necrosis of the donor site, postoperative hyperesthesia, recipient area folliculitis, keloids, bleeding, infection and pyogenic granuloma. Up to this date there are only three reports of KVE developing just after dermatological surgery, including dermabrasion, laser resurfacing, and skin grafting. According to our knowledge, this is the first case of KVE occurring after the FUE procedure. We think that the traumatic effects and skin barrier disruption due to operation and immune alteration due to postsurgical steroid treatment might have precipitated the activation and dissemination of latent herpesvirus infection.

Acral melanoma with satellitosis, disguised as a longstanding diabetic ulcer: a great mimicry.

Acral lentiginous melanoma affects the palms, soles, and nail apparatus. Around 3-15% of all cutaneous melanomas are located on the foot and have a poorer prognosis than melanoma elsewhere. Possible reasons for this prognostic difference may be omitting this area during routine skin check by both the patient and the physicians, in addition to misdiagnosis of melanoma as other benign skin lesions. We describe here an elderly female patient treated for a non-healing foot ulcer interpreted as a diabetic ulcer, which after 2 years was diagnosed as acral melanoma with satellitosis. Histopathological examination of the amputated distal phalanx revealed an advanced stage melanoma with 1·2 cm Breslow thickness and of Clark level 5. Dermoscopy of the bluish papulonodules scattered on the dorsal foot showed characteristic findings described for metastasis of skin melanoma. This case underlines the importance of considering skin malignancies in case of chronic, non-healing ulcers in diabetic patients. Furthermore, we point out the critical significance of skin examination as a whole, and dermoscopy being an important tool in the diagnosis of melanoma and/or cutaneous melanoma metastasis.

Skin problems following septorhinoplasty.

OBJECTIVES/HYPOTHESIS: Septorhinoplasty is one of the most commonly performed plastic surgery procedures in the world. Studies on septorhinoplasty in the literature mainly focus on the surgical procedures and their outcomes, but the general appearance of the nose and nasal skin following surgery is also very important. STUDY DESIGN: Case-control study examining 30 septorhinoplasty patients and 20 septoplasty patients for postoperative skin conditions. RESULTS: There were significant differences identified between the septorhinoplasty group and the septoplasty group with respect to their mean preoperative Global Acne Grading System, Seborrheic Dermatitis Area Severity Index, and visual analog scores (acne, seborrhea, and ecchymosis). CONCLUSIONS: The aim of study was to identify and evaluate postoperative skin conditions among septorhinoplasty patients, as well as the progression and duration of treatment of these conditions. LEVEL OF EVIDENCE: 3b.

Reticular erythematous mucinosis on the midline of the back.

We report the case of a 51-year-old man who presented with reticular macular erythema and erythematous plaques on the midline of the back of 10 years' duration that seemed to worsen on exposure to sunlight. Based on the clinical and histopathologic findings, a diagnosis of reticular erythematous mucinosis (REM) was made. The patient was treated with hydroxychloroquine 400 mg daily and the lesions resolved by the end of the second week of therapy.
