Hypohidrotic Ectodermal Dysplasia Associated with Glucose-6-Phosphate Dehydrogenase Deficiency

Hypohidrotic ectodermal dysplasia (HED) is a syndrome characterized by hypodontia, hypotrichosis, and partial or total ecrine sweat gland deficiency. The most prevalent form of HED is inherited as an X linked pattern. Glucose-6-phosphate dehydrogenase (G-6-PD) deficiency is an X-linked recessive disease, which leads to hemolytic anemia and jaundice. It is expressed in males, while heterozygous females are usually clinically normal. A 12-year-old boy with the complaints of hair and eyebrow disturbances, teeth disfigurement, decreased sweating, and xerosis presented to the outpatient clinic. Dermatological examination revealed sparse hair and eyebrows, conical-shaped teeth, xerosis, syndactylia, transverse grooves, and discoloration of nails. Laboratory findings indicated anemia. His 3-year-old sister also had sparse hair and eyebrows, xerosis, and syndactylia. We learned that the patient had a previous history of neonatal jaundice and a diagnosis of G-6-PD deficiency. Although it has been shown that loci of ectodermal dysplasia and G-6-PD deficiency genes are near to one another, we did not find any case study reporting on occurrence of these two genetic diseases together. With the aspect of this rare and interesting case, the relationship between HED and G-6-PD deficiency was defined.

Annular Plaques on the Tongue: What Is Your Diagnosis?

Geographic tongue is an inflammatory disorder of the tongue characterized by asymptomatic erythematous patches with serpiginous borders. Candidiasis of the tongue may be confused with geographic tongue. A 63-year-old male patient with painful white annular lesions localized to the left side of his tongue is presented. He applied topical corticosteroid and antiinflammatory agents, but his lesions did not respond to those therapies. Using direct mycologic examination and culture, the patient was diagnosed with candidiasis. After systemic and topical antifungal therapy, clinical improvement was observed. With this case, the clinical forms of oral candidiasis were discussed, and it was suggested that the clinical presentation of mucosal candidiasis may vary according to the stage of infection and individual immunity.

Childhood pityriasis rosea inversa without herald patch mimicking cutaneous mastocytosis

Pityriasis rosea is a self-limited inflammatory condition of the skin that mostly affects young adults. Several less common atypical presentations have been reported. A 6-year old girl with red-brown maculopapular eruption sized 0, 5-1 cm in diameter localized on neck, trunk and popliteal region visited our general pediatric outpatient clinic. The eruption was wide spread especially on flexural areas. After consulting dermatologist skin biopsy was performed. According to clinical and histopathological findings as inverse [flexural] pityriasis rosea was diagnosed. For treatment, systemic antihistamine, topical corticosteroid cream and emollient were applied. The lesions healed in two months. Spontaneous healing of the eruption also confirmed the diagnosis of pityriasis rosea. We present this interesting pediatric case to show and discuss pityriasis rosea, atypical presentations, differential diagnosis and the importance of dermatological examination and importance of dermatologic consultation for pediatric patients with skin eruption
