Different Clinical Features of Acral Abortive Hemangiomas.

Some infantile hemangiomas called in literature "minimal or arrested growth hemangiomas" or "abortive hemangiomas" are present at birth and have a proliferative component equaling less than 25% of its total surface area. Often, they are mistaken for vascular malformation. We present five patients (three girls and two boys) with abortive hemangiomas diagnosed between January 2010 and December 2015 localized in acral part of the extremities. They were congenital lesions resembling precursor of hemangiomas but did not show proliferation phase. Immunohistochemical Glut-1 was performed in all of them as a way to confirm the abortive hemangioma diagnosis. The most common appearance was a reticulated erythematous patch with multiple fine telangiectasias on the surface. We remark that one of them presented a segmental patch with two different morphologies and evolutions. The proximal part showed pebbled patches of bright-red hemangioma and presented proliferation and the distal part with a reticulated network-like telangiectasia morphology remained unchanged. We detected lower half of the body preference and dorsal region involvement preference without ventral involvement. The ulceration occurred in three patients with two different degrees of severity.

Dermatosis perforante adquirida: presentación de 8 casos / Acquired Perforating Dermatosis: A Report of 8 Cases

La dermatosis perforante adquirida (DPA) es una enfermedad infrecuente caracterizada por la aparición de lesiones que presentan eliminación transepidérmica de colágeno o fibras elásticas. Afecta a adultos y se asocia a enfermedades sistémicas, principalmente diabetes mellitus e insuficiencia renal. Presentamos 8 casos de DPA, 7 con diabetes mellitus e insuficiencia renal crónica (IRC) y uno con cirrosis alcohólica. Los pacientes con IRC tuvieron un empeoramiento transitorio de la misma coincidiendo con la aparición de la DPA. La creatinina se elevó de media 1,14 mg/dl. El deterioro agudo de la función renal podría estar implicado en la DPA. Se necesitan más estudios para confirmar esta relación

Acquired perforating dermatosis (APD) is an uncommon disease characterized by lesions exhibiting transepidermal elimination of collagen or elastic fibers. APD affects adults and is associated with systemic diseases, mainly diabetes mellitus and renal failure. We present 8 cases of APD. Seven patients had concomitant diabetes mellitus with or without chronic renal failure, and 1 had alcoholic cirrhosis. In the patients with chronic renal failure, the onset of APD coincided with transient worsening of renal function. The mean increase in creatinine concentrations above baseline was 1.14 mg/dL. Acute deterioration of renal function may be involved in APD. Further studies are needed to investigate this association
