Ultrasonographic features of cutaneous myxomas in a patient with Carney complex

Abstract Carney complex is a rare genodermatosis characterized by cardiac and cutaneous myxomas, among other tumors. In the majority of cases, cutaneous myxomas precede the diagnosis of cardiac myxomas, which are the main cause of death in these patients. Despite the fact that the diagnosis of cutaneous myxomas is histopathological, high-frequency ultrasonography plays an essential role in the differential diagnosis with other cutaneous and subcutaneous tumors. The authors of the present study describe, for the first time in the literature, the ultrasonographic features of both variants of cutaneous myxomas, superficial and subcutaneous, in a patient with a Carney complex.

Acropaquias: del signo a la enfermedad / Acropachy: From sign to disease

RESUMEN Las acropaquias, también llamadas dedos en palillo de tambor, se presentan como un aumento de la convexidad ungueal sobre una falange distal engrosada. Su origen es multifactorial, siendo la causa más frecuente las neoplasias, aunque también puede ser idiopático. Pueden encontrarse de forma aislada o formando parte de la osteoartropatía hipertrófica. La importancia de su diagnóstico radica en la alta frecuencia de enfermedad maligna subyacente, por lo que debe ser rápido y exhaustivo. Presentamos 2 casos de pacientes con acropaquias asociados a neoplasia subyacente.

ABSTRACT Acropachy, also called clubbed fingers, presents as increased nail convexity over a thickened distal phalanx. Its origin is multifactorial, with the most frequent cause being neoplasms, although it can also be idiopathic. They can be found in isolation, or as part of hypertrophic osteoarthropathy. The importance of its diagnosis lies in the high frequency of underlying malignant pathology, so it must be rapid and comprehensive. Two cases are presented of patients with acropachy associated with underlying neoplasia.

Pseudoxanthoma elasticum-like papillary dermal elastolysis in non-exposed skin

Abstract Pseudoxanthoma elasticum-like papillary dermal elastolysis is an acquired elastic tissue disorder clinically similar to pseudoxanthoma elasticum in the absence of systemic involvement. Histopathologically, special staining of elastic fibers demonstrates a total or partial band-like loss of elastic fibers in the papillary dermis. Although ultraviolet radiation seems to be one of the main etiological factors in this entity, we report a case of pseudoxanthoma elasticum-like papillary dermal elastolysis on the neck of a woman who wore hijab.

Erythroderma as first manifestation of squamous cell lung cancer: rare case report

Abstract Erythroderma as the first manifestation of a solid organ malignancy is rare. The underlying cancer is a challenging condition to diagnose. There are a few cases of erythroderma in cancer patients reported in the literature. We here describe the case of a 70-year-old man who presented with asthenia, weight loss, dry cough and total body erythema with desquamation over the past month. A chest computed tomography scan showed a nodular lesion, which was finally diagnosed as a squamous cell lung carcinoma. To our knowledge, as an erythroderma presentation, only 13 cases have been reported in the literature. This case report demonstrates the need to search for a neoplasm in patients presenting with erythroderma, particularly in the presence of accompanying debilitating symptoms.
