A case of bullous pemphigoid induced by vildagliptin.

Bullous pemfigoid (BP), an autoimmune disorder, can also be induced by some medications. Vildagliptin is a new drug used to treat diabetes mellitus (DM). Recently, a few cases of vildagliptin-induced BP have been described in the literature. We report a patient with BP in which vildagliptin was thought to be as a possible causative agent. The awareness of BP development risk during gliptin therapy can prevent unnecessary usage of systemic drugs with serious side effects.

Symmetrical drug-related intertriginous and flexural exanthema (Baboon syndrome) associated with infliximab.

BACKGROUND: Symmetrical drug related intertriginous and flexural exanthema (SDRIFE or Baboon syndrome) is a symmetrical contact dermatitis on inverse regions of the body. The disorder is easily differentiated from other drug eruptions by its typical appearance and lack of other concurrent findings. OBSERVATION: A 50-year-old male patient presented to our clinic complaining of a rash that had developed two days after the tenth infliximab infusion for psoriasis and reoccurred after consecutive infusions. The physical examination revealed a bilateral intergluteal, inguinal, abdominal, axillary, antecubital and neck region macular erythematous rash. There were no other systemic findings. The laboratory values were within normal range. The patient was diagnosed with symmetrical drug-related intertriginous and flexural exanthema associated with infliximab treatment based on dermatological findings, histopathology and the results of the provocation test. The lesions resolved permanently after the patient was swiched from infliximab to adalimumab. CONCLUSION: Various cutaneous adverse events of anti-tumor necrosis factor alpha treatment have already been reported. The increased use of these agents can lead to a wider variety of drug-induced skin lesions, such as the reported Baboon syndrome.

New described dermatological disorders.

Many advances in dermatology have been made in recent years. In the present review article, newly described disorders from the last six years are presented in detail. We divided these reports into different sections, including syndromes, autoinflammatory diseases, tumors, and unclassified disease. Syndromes included are "circumferential skin creases Kunze type" and "unusual type of pachyonychia congenita or a new syndrome"; autoinflammatory diseases include "chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature (CANDLE) syndrome," "pyoderma gangrenosum, acne, and hidradenitis suppurativa (PASH) syndrome," and "pyogenic arthritis, pyoderma gangrenosum, acne, and hidradenitis suppurativa (PAPASH) syndrome"; tumors include "acquired reactive digital fibroma," "onychocytic matricoma and onychocytic carcinoma," "infundibulocystic nail bed squamous cell carcinoma," and "acral histiocytic nodules"; unclassified disorders include "saurian papulosis," "symmetrical acrokeratoderma," "confetti-like macular atrophy," and "skin spicules," "erythema papulosa semicircularis recidivans."
