An 18-year-old male patient of consanguineous parents, delivered at full-term by cesarean section and having no changes in neurodevelopment, presented with skin blisters that evolved to eruptions and scars immediately after birth. In childhood, he developed lesions and diffuse tongue hypertrophy, with cutaneous hyperkeratosis and periods of exacerbation after sun exposure or trauma. In regular outpatient appointments with the medical assistant team, neurological symptoms were not observed. He

A biopsy of skin lesion was performed and its histological analysis suggested lipoid proteinosis. Skull radiographic examination demonstrated bilateral and symmetrical parasellar radiodense foci showing a regular structure (figure 1). Analysis of clinical and histological data together with shape and localization of intracranial calcifications is compatible with the presence of amygdalae (figure 1) calcifications, confirming the histological diagnosis (figure 2). Lipoid proteinosis, also known as Urbach-Wiethe disease, is an autosomal recessive genodermatosis caused by mutations in the ECM1 gene 1 and clinically characterized by mucocutaneous lesions, moniliform blepharosis, hoarse voice, and thick short sublingual frenulum that restrict the movement of the tongue 1-5 . Laboratory findings are not specific 1 . Figure 1: Conventional radiographs in anteroposterior (A) and lateral (B) views demonstrate typical bilateral, symmetrical, regular, parasellar radiodense foci corresponding to amygdalae calcifications.
