“…An ‘organoid’ (folliculoepitrichial sweat gland) hamartoma occurred as a nipple‐like lesion on the pinna 1 . Congenital papillomatosis and fibroepithelial hamartoma appear to be the same entity, and have been reported in three pigs 2,3,5 . Lesions were grossly similar to those seen in the piglet reported herein: papillomatous to cauliflower‐like proliferations involving the head, face, jaw, and pinna.…”

“…1 Congenital papillomatosis and fibroepithelial hamartoma appear to be the same entity, and have been reported in three pigs. 2,3,5 Lesions were grossly similar to those seen in the piglet reported herein: papillomatous to cauliflower-like proliferations involving the head, face, jaw, and pinna. However, unlike the piglet reported herein, lesions were not red-purple to pink, and fibroepithelial hyperplasia was seen in skin biopsy specimens.…”

“…Congenital cutaneous hamartomas are very rarely reported in pigs. [1][2][3][4][5] Although rarely reported in dogs and cats, 6,7 epitrichial sweat gland hamartomas have not, to our knowledge, been reported in pigs.…”

A case of multiple congenital epitrichial sweat gland hamartomas in a 2-day-old piglet is presented. The skin lesions were raised, ovoid to linear in configuration, alopecic, red-purple to pink, and cauliflower-like to cerebriform in appearance. Histological examination of skin specimens confirmed a diagnosis of epitrichial sweat gland hamartoma. Complete necropsy examination revealed no other lesions.

Abstract. A 6-month-old, intact, male Weimaraner dog presented to the veterinary teaching hospital for bilateral mucopurulent ocular and nasal discharge that began at approximately 10 weeks of age. A computed tomography scan showed an expansile soft-tissue mass involving both frontal sinuses, the ethmoid regions, and nasal cavities with lysis of the maxillary turbinates and hyperostosis of the walls of the frontal sinus. The dog was euthanized after complications during a trephination and biopsy procedure. At necropsy, a large, tan, papillary, gelatinous mass filled the entire nasal cavity and frontal sinus. The mass was composed of large fronds of loose fibrovascular stroma covered by a single layer of pseudostratified, columnar, ciliated epithelium and intermixed goblet cells. The cells occasionally formed glandular structures that were continuous with the surface epithelium. The mass was diagnosed as a respiratory epithelial adenomatoid hamartoma based on the morphologic appearance.

“…O hamartoma fibroanexial compreende em torno de 2,7% das lesões cutâneas em cães, a qual também pode ser chamada de displasia anexial focal, nevo anexial ou displasia fibroanexial e se assemelha ao hamartoma folículo-sebáceo cístico que ocorre em humanos (LIN; TSAI, 2000;SCOTT et al, 2001). Além deste, existem os hamartomas foliculares, colagenosos, sebáceos, apócrinos, lipofibromatoso, epidérmico e o fibroepitelial (GOLDSCHMIDT; SHOFER, 1992;SCOTT et al, 2001;GROSS et al, 2005;SIPOS et al, 2007;LOURES;CONCEIÇÃO, 2009;MEIRELES et al, 2013).…”

A pele é o maior órgão do corpo do animal, atuando como uma barreira entre o meio externo e interno e suas afeccções perfazem a média de 30% de todo atendimento clínico realizado em pequenos animais. Dentre as lesões não neoplásicas, encontram-se os hamartomas, que são oriundos de um crescimento excessivo de células e tecidos normais no local em que naturalmente se encontram, podendo ocorrer em qualquer tecido ou órgão. O hamartoma fibroanexial pode se apresentar como nódulo solitário, firme, circunscrito, séssil ou de aspecto polipoide, com ou sem alopecia parcial e ulceração. Os anexos cutâneos que se destacam nesse tipo de hamartoma são os folículos pilosos e as glândulas sebáceas, podendo aparecer em aspectos normais ou bizarros, como os folículos pilosos císticos rodeados por lóbulos sebáceos. O objetivo do presente trabalho foirelatar um caso de hamartoma fibroanexial em uma cadela sem padrão racial definido, de aproximadamente sete anos que foi levada à Unidade Hospitalar Veterinária da Universidade Estadual do Ceará (UECE), devido à presença de nódulo em região distal lateral do membro pélvico direito com crescimento lento e progressivo durante um ano. A paciente foi encaminhada para exames complementares de citologia e pré-cirúrgicos. Após excisão cirúrgica, o nódulo foi enviado para avaliação histopatológica. Microscopicamente, a lesão exibiu uma estrutura nodular intradérmica composta por tecido fibroso abundante, envolvendo e segmentando estruturas anexiais incompletas, representadas por glândulas sebáceas e folículos pilosos, alguns destes rôtos, suscitando intenso processo inflamatório piogranulomatoso. Os achados macro e microscópicos foram determinantes para o diagnóstico da lesão como hamartoma fibroanexial.
