Verrucous hemangioma and histopathological differential diagnosis with angiokeratoma circumscriptum neviforme

Abstract: Verrucous hemangioma is a rare vascular skin disorder with an immune profile similar to vascular neoplasms, but with behavior and evolution of vascular malformations. Its main differential diagnosis is angiokeratoma circumscriptum neviforme, with an almost indistinguishable clinical presentation because both diseases appear as erythematous patches that evolve to violaceous plaques, becoming scaly and even verrucous, most commonly affecting the lower limbs. Histopathology is crucial for the correct diagnosis: while in angiokeratoma the vascular alterations are limited to the papillary dermis, verrucous hemangioma extends deep into the dermis, reaching the subcutaneous tissue.

Genital angiokeratoma in a woman with Fabry disease: the dermatologist's role

Abstract: Fabry disease is a rare lysosomal storage disorder, inherited in an X-linked manner. It is characterized by the deficiency of the enzyme alpha-galactosidase, leading to a buildup of glycosphingolipids in the cells. Angiokeratoma is one of the cutaneous manifestations of this condition, and it helps making the diagnosis. The typical site involves the genital area in men and lumbosacral, buttocks and trunk region in both sexes. We report a case of genital angiokeratoma in a woman with Fabry disease. The diagnosis is through molecular analysis and, when made early, starting treatment reduces the morbidity and mortality of the disease. Thus, the dermatologist has an important role in the identification of angiokeratoma as a cutaneous marker, and the knowledge of its different presentations is essential for the early diagnosis and management of Fabry disease.

Multiple giant angiokeratoma of Fordyce on the shaft of the penis masquerading as keratoacanthoma

The term 'angiokeratoma' includes a wide range of dermatological conditions of hyperkeratotic vascular disorders with a similar histologic combination of hyperkeratosis and superficial dermal vascular ectasia. Angiokeratomas can be classified into localized and systemic forms. Angiokeratoma of Fordyce (AKF) is a localized form of angiokeratoma, clinically characterized by 1- to 6-mm, black, blue, or dark red, dome-shaped papules located on the scrotum, shaft of penis, labia majora, clitoris, inner thigh, and lower abdomen. We describe herein a case of giant angiokeratoma of Fordyce on shaft of the penis in an elderly man, clinically masquerading as keratoacanthoma.

Fabry disease: clinical and genotypic aspects of three cases in first degree relatives

Fabry disease is an X-linked, lysosomal storage disease caused by the inherited deficiency of the enzyme α-galactosidase A. The diagnosis is usually late, with renal, cardiovascular and/or cerebral complications that reduce life expectancy. Angiokeratomas are asymptomatic lesions present as the initial manifestation and usually less appreciated. Their detection is important for early diagnosis and institution of treatment with enzyme replacement therapy, which prevents late complications reducing morbidity and mortality. We report a case of a male teenager with acroparestesias and angiokeratomas. Family medical research discovered that his mother and brother had similar signs and symptoms and that the three patients had the same mutation in the gene encoding the enzyme, confirming the diagnosis.

Acral pseudolymphomatous angiokeratoma: case report and literature review / Angioqueratoma pseudolinfomatoso acral: relato de caso e revisao da literatura

The authors describe a case of a female patient with Acral Pseudolymphomatous Angiokeratoma of Children, known as APACHE. It is a rare benign cutaneous disease, of unknown etiology, characterized by multiple, asymptomatic erythematous-violaceous papules and nodules, usually located unilaterally with acral distribution. Today, this denomination is questionable, since there are published reports of this disease in adults and in different locations. Clinically, it is similar to an angiokeratoma, whereas hystologically, it corresponds to a distinct type of pseudolymphoma. The immunohistochemical study is required to distinguish APACHE from cutaneous lymphoma.

Relata-se o caso de uma paciente com diagnóstico de angioqueratoma pseudolinfomatoso acral, conhecido por sua sigla em inglês APACHE - Acral Pseudolymphomatous Angiokeratoma of Children. É uma doença cutânea benigna, rara, de etiologia desconhecida, caracterizada por múltiplas pápulas e nódulos eritêmato-violáceos assintomáticos, de localização geralmente unilateral e acral. Atualmente, questiona-se esta denominação, já que há relatos na literatura do quadro em adultos e em outras localizações. Clinicamente, é similar a um angioqueratoma, porém, histologicamente, corresponde a um tipo distinto de pseudolinfoma. O estudo imuno-histoquímico é necessário para diferenciação dos linfomas cutâneos.

Enfermedades por depósito lisosomal: diagnóstico a partir de lesiones cutáneas / Lysosomal storage diseases, diagnosis from skin lesions

Las enfermedades por depósito lisosomal (EDL) son un grupo heterogéneo de más de 40 dolencias genéticas, debidas a la deficiencia de diversas enzimas encargadas de metabolizar sustancias dentrode los lisosomas. Estas macromoléculas se depositan dentro de las organelas de múltiples órganos y dan lugar a diversos signos y síntomas.Muchas de estas enfermedades tienen manifestaciones cutáneas, e incluso en algunas oportunidades es el dermatólogo quien sospecha el diagnóstico a partir de las lesiones en piel.En el presente trabajo se describen 8 pacientes con EDL, diagnosticados en nuestro servicio entre 2009 y 2010, en los cuales las lesiones en piel fueron la clave para arribar al diagnóstico.Cinco pacientes presentaban enfermedad de Fabry (un varón y 4 mujeres), uno mucopolisacaridosis 2 (sexo masculino), uno beta-manosidosis (sexo masculino) y el último galactosialidosis (sexo femenino).Los angioqueratomas fueron la manifestación cutánea más frecuente, y la clave diagnóstica en los pacientes con Fabry, el paciente con manosidosis y la paciente con galactosialidosis, mientras que la lesión en piel que llevó a sospechar mucopolisacaridosis 2 fueron manchas mongólicas aberrantes, algunas lenticulares, que comprometían el tronco.En cuatro pacientes el diagnóstico se confirmó por estudios enzimáticos en gota de sangre en papel de filtro, leucocitos y/u orina. En cinco pacientes (uno de los cuales ya había sido diagnosticado deforma bioquímica) se realizó estudio molecular. En todos los pacientes se hicieron los estudios complementarios necesarios para evaluar extensión del compromiso extracutáneo y necesidad de tratamientoespecífico (en aquellos pacientes en los cuales su enfermedad de base dispone de terapia de reemplazo enzimático). En uno de los pacientes con Fabry se inició terapia específica.El interés de nuestro trabajo radica en mostrar distintas EDL en las cuales el rol del dermatólogo fue fundamental para arribar al diagnóstico, resaltando..

Lysosomal-storage disorders are a group of more than 40 heterogeneous hereditary diseases dueto the deficiency of various lysosomal enzymes, in charge of the metabolization of macromolecules,with accumulation of the undigested substances inside those organelles througout severalorgans, deriving in the multiple symptoms and signs of these diseases.A great number of these diseases may have cutaneous lesions, and in many cases the dermatologistmay be the one to suggest the diagnosis.We describe eight patients with lisosomal storage diseases diagnosed at our hospital during 2009and 2010, on whom the cutaneous lesions were the clue to the diagnosis. Five patients were diagnosed as Fabry´s disease (1 male and 4 females), one as mucopolisaccharidosis2 (male), one as mannosidosis (male) and the last one as galactosyalidosis (female). Angiokeratomaswhere the most frequent cutaneous manifestation, and the key to the diagnosis inFabry’s, beta mannosidosis and galactosyalidosis, while aberrant and lenticular mongolian spotson the trunk led us to the diagnosis of mucopolissacharidosis 2.On four patients the diagnosis was confirmed by biochemical work-up. On five patients (one ofthem had already been confirmed with biochemistry) a genetic study was also performed.On all the patients studies where performed to evaluate the extension of the systemic disease andthe need of a specific treatment (for those diseases where it is available). One of the patients withFabry´s disease started the treatment soon after the diagnosis.We would like to emphasize the fundamental role of the dermatologist in diagnosing these diseases,stressing not only the academic importance of these rare diseases but also the possibility ofstarting in many of them specific enzyme replacement treatment.

Existen descriptos diferentes tipos de angioqueratomas: los localizados que originan trastornos estéticos y los que tienen implicancia sistémica. Presentamos un caso en una adolescente de sexo femenino con angioqueratoma cirsunscrito en lengua.

Angioqueratoma circunscrito interglúteo: reporte de un caso / Intergluteal angiokeratoma circumscriptum: report of one case

Introducción: el término angioqueratoma se aplica a un conjunto de enfermedades con una base clínica de lesiones vasculares comunes. El objetivo de este reporte es comunicar el hallazgo de un angioqueratoma interglúteo. Caso clínico: hombre de 26 años quien desde la infancia presentó tumoración interglútea, manejada en varias ocasiones sin resultados. Cuando acudió a la consulta que motivó este reporte, presentaba tumoración verrucosa interglútea dolorosa y sangrante de 7 x 4 cm, de contornos irregulares. Se efectuó resección quirúrgica amplia. Los resultados histopatológicos indicaron angioqueratoma circunscrito con bordes libres de tumor. Discusión: de los cinco tipos de angioqueratomas descritos en la literatura (corporal difuso, de Mibelli, de Fordyce, solitario y corporal circunscrito), en nuestro caso se identificó angioqueratoma circunscrito por las características físicas y anatomopatológicas de la tumoración. El diagnóstico diferencial debe establecerse con el hemangioma verrucoso y la enfermedad de Fabry tipo II (angioqueratoma corporal difuso). Conclusiones: la patogénesis del angioqueratoma es desconocida y el tratamiento recomendado es el quirúrgico.

BACKGROUND: The term angiokeratoma is applied to several diseases with cutaneous vascular lesions. CLINICAL CASE: A 26-year-old male presented with an intergluteal tumor from childhood until the present time, which was treated on several occasions without results. The patient presented to the hospital complaining of a painful and bleeding intergluteal tumor. DISCUSSION: Five types of angiokeratomas have been described (angiokeratoma corporis diffusum, angiokeratoma of Mibelli, angiokeratoma of Fordyce, solitary angiokeratoma and angiokeratoma corporal circumscriptum). This patient was identified with an angiokeratoma circumscriptum by pathological and physical characteristics of the tumor. Differential diagnosis is with verrucous hemangioma and the Fabry disease type II (angiokeratoma corporis diffusum). CONCLUSION: Pathogenesis is unknown and surgery is the recommended treatment.

Papillary endothelial hyperplasia in angiokeratoma.

Papillary endothelial hyperplasia (Masson's tumour) is a reactive proliferation of endothelium producing papillary structures with fibrovascular cores. Dilatation, stasis and accompanying inflammation have been incriminated as the inciting events, evident by the presence of this lesion in haemorrhoids, urethral caruncles and laryngeal polyps. We present here a case of papillary endothelial hyperplasia in angiokeratoma hitherto undescribed despite sharing common etiopathogenetic features of dilatation and stasis with other aforementioned lesions.

O angioqueratoma vulvar é semelhante ao angioqueratoma do escroto, tipo Fordyce, e pode ser encontrado como lesäo única ou múltipla, de crescimento popular, globular ou verrucóide, associada muitas vezes a sangramento local intermitente. Os autores comentam o tratamento e a orientaçäo nestes casos

Angioqueratoma papuloso zoniforme no metamérico (Fabry tipo II) / Zoniform papulous angiokeratoma (Fabry type II)

Se presenta un caso de angioqueratoma papuloso zoniforme no metamérico distribuido por sectores del brazo y antebrazo de una enferma de 43 años de edad, que padecía la enfermedad desde la primera infancia. Esta forma clínica es asimilada con ciertas reservas a la enfermedad de Fabry tipo II, debido a los hechos clínicos tan diferentes que hacen principalmente a la distribución y al aspecto lesional, pequeñas pápulas de uno a cuatro milímetros. Se hace una revisión de todo el conjunto de los angioqueratomas a través de dos de sus clasificaciones más usuales. Se establecen los diagnósticos diferenciales más importantes a los que la variedad neviforme y circunscripta obliga. Se enfatiza la diferenciación de este caso zonal no metamérico y micropapuloso con la forma circunscripta neviforme tradicional de la enfermedad de Fabry tipo II, así como con el Fabry tipo I
