Angioma serpiginosum: report of an unusual acral case and review of the literature.

We report the case of a 35-year-old woman with deep-red asymptomatic macules on the plantar and dorsal skin of the right great toe. Histopathologic findings were compatible with Angioma serpiginosum. Immunohistochemical stains for estrogens and progesterone receptors were negative. Dermoscopy showed an erythematous parallel ridge pattern with double rows of irregular dots and globules. We report an unusual case of angioma serpiginosum with acral volar skin involvement. The dermoscopic features described may aid in the diagnosis of AS in this specific skin area. Acral volar skin involvement must be included in the clinical spectrum of Angioma serpiginosum and in the differential diagnosis of acral vascular lesions.

[Exudative onycholysis and acute bacterial paronychia related to BIBF-1120 and paclitaxel: response to topical therapy]. / Onicólisis exudativa y paroniquia bacteriana aguda en relación con BIBF-1120 y paclitaxel: respuesta a la terapia tópica.

A case of a 50 years-old breast cancer patient treated with weekly paclitaxel and BIBF 1120 is reported herein. At the end of the twelfth cycle of chemotherapy, the patient developed distal onycholysis with intense hyponychium serous exudates, pain and malodor in all her fingernails. It was treated with topical fusidic acid and 1% methylprednisolone aceponate two times daily, with an excellent clinical response from the first three days of treatment. Bacterial paronychia with nail plate loss of the fifth left fingernail was observed a week after the topical therapy was started, with positive cultures for Methicillin susceptible Staphylococcus aureus. There are few reported cases of exudative onycholysis associated with chemotherapy. However, these are especially related to paclitaxel. No recurrences of nail disturbances were observed weeks after the end of chemotherapy. Topical corticosteroids and fusidic acid could be considered as a therapeutic option when exudative onycholysis related to paclitaxel is established

Se presenta el caso de una paciente de 50 años de edad con cáncer de mama tratada con paclitaxel y BIBF 1120 semanal. La paciente desarrolló al final del duodécimo ciclo de quimioterapia una onicólisis distal, con exudado seroso intenso en el hiponiquio, dolor y mal olor en todas las uñas de las manos. Se trató con ácido fusídico tópico y aceponato de metilprednisolona al 1% dos veces al día, con una excelente respuesta desde los tres primeros días de tratamiento. A la semana de iniciar la terapia tópica, se observó una paroniquia bacteriana con la pérdida de la uña del quinto dedo de la mano izquierda, con cultivos positivos para Staphylococcus aureus sensible a meticilina. Hay pocos casos publicados de onicólisis exudativa asociada a quimioterapia. Sin embargo, están especialmente relacionados con paclitaxel. No se observaron recurrencias de las alteraciones ungueales semanas después de culminar la quimioterapia. Los corticoides tópicos y el ácido fusídico podrían ser considerados como una opción terapéutica cuando la onicólisis exudativa relacionada con paclitaxel esté establecida.

Dermoscopy of acral angioma serpiginosum.

Angioma serpiginosum (AS) is an unusual vascular disorder that typically affects female patients, begins in childhood and stabilizes in adulthood and not frequently involve acral skin. We herein present a 13 year-old girl with an asymptomatic erythematous punctuate first noticed on the right palm three years ago, with a proximal serpiginous progression up to the forearm. On examination there was a nonblanching erythematous punctuate on the palm and the inner aspect of right hand and forearm. Dermoscopy showed an erythematous parallel ridge pattern with some red globules and dots spreading on a linear arrangement, and the acrosyringia openings were not affected. Histopathological study showed dilated capillaries in the dermal papillae. This feature is consistent with angioma serpiginosum (AS). To the best of our knowledge, this is the first report that shows a dermoscopic image of a palmar AS. The dermoscopic pattern described in this case could aid in the diagnosis of AS and could add a value in the differential diagnosis with vascular lesions on acral skin.

Cutaneous leishmaniasis with histopathologic pattern of non-necrotizing granulomatous dermatitis in patients treated with adalimumab.

Human leishmaniasis produced by Leishmania infantum is endemic in Mediterranean countries. In the context of a leishmaniasis outbreak in the town of Fuenlabrada, Madrid, Spain, we had two patients with cutaneous leishmaniasis that developed non-necrotizing cutaneous granulomas. They had both been receiving anti-TNF treatment with adalimumab for rheumatic diseases. Neither of them developed visceral disease and did not require anti-TNF treatment withdrawal to control the cutaneous disease. It is well known that anti-TNF therapy is associated with opportunistic diseases, especially with those in which granuloma formation is an important part of the host defence, as in tuberculosis. We think that granuloma formation through activation of Toll-like receptor-9 and via induction of a Th17 response may be precipitated by the parasites in the dermis.

Validation of dermoscopy as a real-time noninvasive diagnostic imaging technique for actinic keratosis.

OBJECTIVE: To validate dermoscopy as a real-time noninvasive diagnostic imaging technique for actinic keratosis (AK). DESIGN: Prospective study to validate a diagnostic test. SETTING: Dermatology department of a tertiary university hospital in Fuenlabrada, Madrid, Spain. PATIENTS: A total of 178 patients with a clinical diagnosis of AK participated in the study. MAIN OUTCOME MEASURES: An independent blinded comparison was performed between dermoscopy results and histopathological findings, the gold standard for the diagnosis of AK. All the patients underwent both diagnostic tests. RESULTS: One hundred seventy-eight lesions were evaluated. The concordance between dermoscopy results and histopathological findings was 0.917. The sensitivity of dermoscopy for the diagnosis of AK was 98.7%, with a specificity of 95.0%, a positive likelihood ratio of 19.74, and a negative likelihood ratio of 0.01. A diagnostic algorithm that combined follicular openings and erythematous pseudonetwork demonstrated a sensitivity of 95.6% and a specificity of 95.0% for the diagnosis of AK. CONCLUSIONS: The sensitivity and specificity of dermoscopy for the diagnosis of AK were high, as was the concordance between dermoscopy results and histopathological findings. As a real-time noninvasive diagnostic imaging technique for AK, dermoscopy may be incorporated in the management of patients with these lesions.

Nevus lipomatosus superficialis with a folliculosebaceous component: report of 2 cases.

Nevus lipomatosus superficialis (NLS) is an uncommon hamartomatous lesion of the skin characterized by the presence of clusters of mature fat cells among the collagen bundles of the dermis. Usually, the number of adnexal structures is reduced in NLS as compared to the normal adjacent skin, but their morphology is not altered. Nevertheless, in some instances, associated pilar abnormalities have been reported. We here report 2 cases of NLS with disorganized pilosebaceous units. The follicular structures were dilated and showed infundibular type keratinization and there were numerous mature sebaceous lobules radiating from them resembling the histology of a folliculosebaceous cystic hamartoma (FSCH) or a sebaceous trichofolliculoma. Only 2 cases of NLS with FSCH have been previously reported. Our cases represent examples of a very rare hamartomatous cutaneous lesion composed of mesenchymal and epithelial components.

Pigmented axillary nodule: carcinoma of an ectopic axillary breast.

BACKGROUND: Ectopic mammary tissue appears in humans owing to an incomplete embryologic regression of the mammary ridges. The same pathology that affects normally positioned breasts, including carcinoma, can occur in ectopic mammary tissue. OBJECTIVE: The objective was to present the case of a 43-year-old woman who developed a ductal mammary carcinoma of ectopic breast tissue. METHODS: We describe the patient's history, the histologic diagnosis, and the therapy carried out. We also discuss the clinical differential diagnosis and current management options. RESULTS: The patient developed a ductal mammary carcinoma in the axilla, which is the most common site for the occurrence of carcinoma of ectopic breast tissue. She has been sucessfully treated with surgery, lymphadenectomy, radiotherapy, and chemotherapy. Accessory mammary tissue is a relatively frequent incidental finding, whereas carcinoma of ectopic tissue is very rare. CONCLUSIONS: Carcinoma occurring in ectopic breast tissue remains rare, but this diagnosis must be suspected when confronted with any axillary nodule. The prognosis is similar to carcinoma of normal breast in the same tumor, node, metastasis stage, although it has a higher rate of lymph node involvement. There is no consensus on the advisability of excising ectopic mammary tissue.
