Tattoos: Very Popular, Not So Innocent.

Tattooing is a popular practice worldwide. Its origin dates back to the year 5000 BCE with a frozen mummy and travels across time through diverse cultures and places until it reaches the modern occidental world. Inks and materials used for tattooing are poorly controlled and carry potential risks of skin reactions. The procedure itself is also not innocuous. In this review, different types of tattoos are mentioned and associated dermatologic conditions are discussed. Unfortunately, treatment and removal procedures are often poor in effectiveness and lead to unwanted results. Combining different lasers may be a suitable option that requires further investigation.

RAVEN: forma particular de nevo epidérmico. Primer caso argentino / RAVEN: particular type of epidermal nevus. First argentinian reported case

Los nevos epidérmicos (NE) son hamartomas cutáneos de baja frecuencia originados en células pluripotenciales del ectodermo embrionario. Se reconocen diferentes variantes según su morfología y topografía. En 2012 se introdujo una nueva forma clínica con característicassingulares: el RAVEN, acrónimo de rounded and velvety epidermal nevus.Presentamos el primer caso argentino de esta variedad de nevo epidérmico y resaltamos sus características principales...

Multiple cystic disease: K17 dysfunction?

Our patient is a 29-year-old woman without any previous disease who presented with different kinds of lesions on her face, neck, and chest. She first noticed the lesions 10 years ago and, since that time, they have become more numerous. She has no affected relatives. On physical examination, she had multiple cystic lesions on her neck, chest, and vulva, which were between 0.3 cm and 1 cm and skin-colored or yellowish (Figure 1). She presented with small, white papules on her face measuring approximately 0.2 cm, localized on her forehead and cheeks. Some of these papules had a blueish appearance (Figure 2). She also presented clinically typical eruptive syringomas on her upper and lower eyelids and neck and multiple facial milia. Finally, a sacrococcygeal pilonidal cyst was diagnosed and surgically removed. Her nails and teeth were clinically normal. Biopsies of each kind of lesion were performed, with the following results: (1) neck cystic lesion: steatocystoma; (2) small, white facial papule: eccrine hidrocystoma; (3) blueish facial papule: apocrine hidrocystoma; and (4) small neck papule: syringoma (Figure 3). With these findings, our diagnosis was steatocystoma multiplex with multiple eccrine and apocrine hidrocystomas, eruptive syringomas, and sacrococcygeal pilonidal cyst.

Syndromic nevoid hypermelanosis: description of seven cases with a 10-year follow up.

Skin lesions can often be the only sign of an underlying systemic abnormality which will require further investigation. Several syndromic conditions are diagnosed after their cutaneous marker, which is in most cases a nevus. We report a neurocutaneous condition which we named "syndromic nevoid hypermelanosis" (SNH). We studied seven patients who presented with hyperpigmented disseminated macules (melanotic or pigmented nevi) as a cardinal sign. Neurological abnormalities were detected in all cases and skeletal dysmorphism in four. In spite of the genetic alteration that may be the cause of this disease, dermatologists should be able to diagnose it based on its semiological features and distinguish it from other neurocutaneous conditions. We consider SNH to be a distinct clinical entity that has not been clearly defined until now.

Actinomyces meyeri cutaneous actinomycosis.

Actinomyces meyeri cutaneous actinomycosis is a very rare disease. It often results from contiguous dissemination of an underlying focus. We report a case of pulmonary actinomicosis with secondary cutaneous involvement which led to the diagnosis. A 51-year-old man presented with an indurated, erythematous plaque on his right chest wall. He had been diagnosed with pneumoniae one month prior ago and received antibiotic treatment but symptoms persisted. Fibrobroncoscopy was normal and bronchoalveolar lavage samples were negative. The cutaneous plaque evolved with fistulization and drainage of serohematic material with white grains. Actinomyces meyeri was cultured from bacteriologic samples. Ceftriaxone and doxiciclin were administered for a total of 12 months with complete resolution of the clinical condition.

Síndrome de Reynolds: asociación de cirrosis biliar primaria y esclerodermia. A propósito de dos casos / Reynolds Syndrome: association of primary biliary cirrhosis and scleroderma. Report of two cases

El síndrome de Reynolds consiste en la combinación de cirrosis biliar primaria y esclerodermia; se encuentra frecuentemente asociado a otras enfermedades autoinmunes constituyendo un síndrome autoinmune múltiple. La importancia de conocer esta patología radica en la posibilidad de realizar un diagnóstico precoz de cirrosis biliar primaria la cual marcará el pronóstico del paciente, ya que su frecuencia en los pacientes con esclerodermia está subestimada.
