Angiolymphoid hyperplasia with eosinophilia on the tongue.

Angiolymphoid hyperplasia with eosinophilia (AHE) is a benign reactive vascular lesion characterized by a proliferation of small to medium sized vascular structures lined by epithelioid endothelial cells. We report a 75-year-old woman with a 1-month history of a painful ulcer on the tongue. Histopathological findings confirmed a diagnosis of angiolymphoid hyperplasia with eosinophilia. The tongue is an unusual site for this lesion. The treatment of choice for AHE is surgical excision.

Mondor's disease.

Mondor's disease (MD) is a rare condition, which is considered a thrombophlebitis of the subcutaneous veins. It commonly occurs on the anterolateral thoracoabdominal wall, but it can also occur on the penis, groin, antecubital fossa and posterior cervical region. The clinical features are a sudden and typically asymptomatic onset of a cord-like induration, although some patients report a feeling of 'strain'. It is a self-limiting process that lasts a short period of time, which may be the reason why there are few reports about its diagnosis and treatment. Its pathogenesis has remained unclear, because of the lack of methods to reliably differentiate between veins and lymphatic vessels. Immunohistochemical staining for CD31 and D240 has been identified recently as the best method to distinguish small veins from lymphatic vessels, making it a valuable technique in diagnosing not only MD, but also many other diseases in which veins or lymphatic vessels are affected. MD has been associated with several systemic diseases such as breast cancer and hypercoagulability states, thus laboratory studies are recommended to exclude any possible systemic disorders. As this condition is usually a benign and self-limiting process, vigorous treatment is only recommended when the process is symptomatic or recurrent.

Immunohistochemical clues to the diagnosis of Mondor's disease of the penis.

Mondor's disease of the penis is usually a benign, self-limiting process of acute onset. To date, there have been few studies about its diagnosis and treatment. It is difficult to differentiate MD of the penis from sclerosing lymphangitis of the penis, because the symptoms, epidemiology and aetiology are similar, and because veins are histologically very similar to lymphatics. We report a case of MD in which immunochemical markers such as CD31 and D240 allowed us to specifically discriminate between the small vein and lymphatic vessels. This is important not only for the recognition of MD at any site, but for many other diseases in which veins or lymphatic vessels are affected.

[Lipedematous scalp]. / Cuero cabelludo lipedematoso.

Lipedematous scalp is a rare condition first described by Cornbleet in 1935. An increased thickness of subcutaneous tissue in the scalp gives rise to a soft spongy appearance of the surface and occasionally causes pruritus and pain in the affected area. When hair loss is also associated with the condition, it is described as lipedematous alopecia. To date, 10 cases of lipedematous scalp and 13 of lipedematous alopecia have been reported. We present the case of a 77-year-old white woman who developed dysesthesia on her scalp 5 months after the death of her husband. Biopsy revealed subcutaneous tissue thickening that even extended to the dermis. Computed tomography showed thickening of subcutaneous tissue at the vertex and in the occipital region. We diagnosed a new case of lipedematous scalp in a white woman. This case highlights the importance of differential diagnosis in cases of dysesthetic syndrome of the scalp.

Cuero cabelludo lipedematoso / Lipedematous Scalp

El cuero cabelludo lipedematoso es una rara entidad que fue descrita por Cornbleet en 1935, en la que un aumento del tejido subcutáneo del cuero cabelludo produce un aspecto suave y esponjoso de la superficie del mismo y ocasionalmente prurito y dolor de la zona afectada. Cuando además esta condición produce alopecia se denomina alopecia lipedematosa. Hasta la fecha se han descrito 10 casos de cuero cabelludo lipedematoso y 13 de alopecia lipedematosa. Presentamos el caso de una mujer de 77 años de raza caucásica con sensación disestésica en el cuero cabelludo 5 meses después de la muerte de su esposo. Realizamos una biopsia donde se observaba un engrosamiento del tejido graso subcutáneo que incluso se extendía a la dermis. Una tomografía computarizada mostraba este engrosamiento de los tejidos subcutáneos en el vértex y el área occipital. Diagnosticamos un nuevo caso de cuero cabelludo lipedematoso en una mujer caucásica, destacando la importancia del diagnóstico diferencial con el síndrome disestésico del cuero cabelludo (AU)

Pioderma gangrenoso después del parto por cesárea / Pyoderma gandrenosum following cesarean delivery

Presentamos el caso de una mujer de 30 años, primípara, que 5 días después del parto por cesárea presenta dehiscencia de uno de los extremos de la herida quirúrgica y una lesión en la pierna, que evolucionó a una úlcera bien constituida, ambas lesiones muy dolorosas. Fue diagnosticada inicialmente de infección cutánea y posteriormente de pioderma gangrenoso superficial; se trataron las lesiones con corticoides tópicos con buena respuesta al tratamiento. Tras el estudio de la paciente no se encontró patología subyacente. La asociación del pioderma gangrenoso con el embarazo o parto por cesárea se encuentra en la literatura como casos individuales. En la actualidad no se conoce la etiología del pioderma gangrenoso, aunque algunas teorías apuntan a un trastorno de la función inmunológica. Se sabe que la gestación determina un estado de inmunotolerancia que podría tener algún papel en el desarrollo del pioderma gangrenoso; futuras investigaciones podrán aclarar la relevancia de esta asociación (AU)

We describe the case of a 30-year-old woman who, 5 days after giving birth to her first child by cesarean section, presented with dehiscence of one end of the surgical wound and a lesion on her leg that developed into a well-defined ulcer; both lesions were very painful. The patient was initially diagnosed with as kin infection and later with superficial pyoderma gangrenosum. The lesions were treated with topical corticosteroids and a good response was observed. No evidence was found of underlying disease. Isolated cases of pyoderma gangrenosum associated with pregnancy or cesarean delivery have been reported in the literature. The etiology of pyoderma gangrenosum is currently unknown, but some theories suggest an immunologic mechanism. Gestation is known to generate a state of immune tolerance that could play a role in the development of the disease and future studies may help to clarify the significance of this association (AU)
