Skin tumours reported in rabbits

Apocrine gland hyperplasiaUnencapsulated cystic, multiloculated and multilobulated mass consisting of numerous, variably sized cystic spaces and tubules supported by a moderately dense fibrovascular stroma (Benato and Morrison 2011)
Apocrine gland adenocarcinomaLarge subcutaneous cyst and firm mass located in the cutaneous tissue reported on the abdominal wall. It was composed of tubular and restiform proliferations of multi-angular to spindle-shaped small epithelial cells (Miwa and others 2006)
Apocrine carcinomaEpithelial tumours characterised by well-dermacated proliferation of cuboidal to columnar cells with basilar-oriented, moderately pleomorphic nuclei, which form tubules, acini or cysts (von Bomhard and others 2007)
Basal cell tumourFirm and slightly elevated intradermal masses. They are often pigmented and found primarily on head, neck and legs. They can become ulcerated if not removed (Kanfer and Reavill 2013)
Cutaneous lymphomaClinical signs include alopecia, erythema and crusting that can be localised or diffuse. Neoplastic lymphocytes can be found in the skin and lymph nodes (Ritter and others 2012)
Mammary gland tumourSmall subcutaneous nodules that grow quickly and ulcerate if not treated (Kanfer and Reavill 2013)
Sebaceous carcinomaPoorly defined firm, flat yellow masses with a multilobular proliferation of pleomorphic cuboidal to elongated cells with indistinct cell borders and variably vacuolated amphophilic cytoplasm. It can be found on pinnae and feet (von Bomhard and others 2007)
Squamous cell carcinomaReported from the subungual region and haired skin in the metatarsal area and medial canthus of the eyelid. All had a marked desmoplastic response (von Bomhard and others 2007).
Spindle cell sarcomaFirm subcutaneous masses, that can be found anywhere in the body (Kanfer and Reavill 2013)
Squamous papillomaBenign growth with irregular papillary projections of the hyperplastic stratified squamous epithelium. Generally found on the head (Kanfer and Reavill 2013)
TrichoepitheliomaWell-demarcated and encapsulated, multilobular proliferation of cells with differentiation into the three segments of the hair follicle (von Bomhard and others 2007)
