Acquired perforating dermatosis: a report of 8 cases.

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 1.14mg/dL. Acute deterioration of renal function may be involved in APD. Further studies are needed to investigate this association.

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.

Giant neck liposarcoma with pathological clavicular fracture.

Liposarcomas generally originate in the extremities or retroperitoneum, they are very unusual in the head and neck region, and extremely rare in the thorax. The mainstay of treatment for liposarcomas is surgical excision. We report a very unusual case, not reported before to our knowledge, of a well-differentiated liposarcoma arising from the supraclavicular fossa that produces a pathological clavicular fracture. The patient underwent complete resection of the lesion, without damage of the cervical nerves. Eight months after the surgery the patient is free of recurrence. We demonstrate that giant liposarcomas can be resected completely without morbidity.

[Hyposmia, fetid rhinorrhea and facial pain caused by a maxillary aspergilloma]. / Hiposmia, rinorrea fétida y algias faciales por aspergiloma maxilar.

In the last few years an increase has been observed in the incidence of fungal sinusitis in immunocompetent subjects. We present a case of mycotic sinusitis in a 12-year-old patient, in which there were several aspects that could have made the diagnosis more difficult, thus delaying her definitive treatment. This case illustrates how to arrive at a correct diagnosis of this pathology. It must be based on the histological and radiological studies, but always without forgetting a key aspect as it is a suspected diagnosis. The treatment of fungal sinusitis is surgical, and currently, endoscopic sinus surgery is the choice. We describe the clinical characteristics of this pathology and the diagnostic methods required.
