Abstract
BACKGROUND Epitheliotropic lymphoma is an uncommon cutaneous malignancy of T lymphocytes. Limited information is available regarding the treatment and outcome of dogs with this disease. OBJECTIVES To evaluate the treatment outcome and toxicity profile of isotretinoin in dogs with epitheliotropic lymphoma. ANIMALS Twelve dogs with a diagnosis of epitheliotropic lymphoma were included. MATERIALS AND METHODS A medical database was searched for dogs diagnosed with epitheliotropic lymphoma and treated with isotretinoin between 2010 and 2021. Diagnosis, treatment details and tumour response were recorded for 12 dogs. RESULTS All lesions resolved in four of 12 (33%) treated dogs. Lesions visibly improved in a further three dogs, giving a response rate of 58%. Two dogs' lesions remained unchanged and three progressed despite therapy. Adverse effects occurred in three dogs (25%), all of which were rapidly resolving or not affecting quality of life. CONCLUSION Isotretinoin treatment was a well-tolerated and effective treatment for canine epitheliotropic lymphoma.

Abstract
Canine cutaneous lymphoma is an uncommon lymphoma in dogs. Most canine cutaneous lymphoma cases have a T-cell origin. Canine cutaneous T-cell lymphoma (CTCL) is classified into epitheliotropic and nonepitheliotropic cutaneous lymphomas, and each type of lymphoma is subclassified into several histological subtypes. Limited information is available regarding the prognostic significance of clinical variables and histopathological subtypes in dogs with CTCL. This retrospective study aimed to investigate the influence of clinical variables and histopathological subtypes on the prognosis of dogs with CTCL. Forty-six dogs diagnosed with CTCL by histopathological examination were included. Histopathological specimens were reexamined and classified into CTCL subtypes. The influence of the type of skin lesion, histopathological subtype, haematological examination results and treatment response on the overall survival time (OS) was examined. Thirty-one dogs were diagnosed with epitheliotropic CTCL (mycosis fungoides in 28 dogs; pagetoid reticulosis in 3 dogs) and 15 dogs were diagnosed with nonepitheliotropic CTCL (anaplastic large T-cell lymphoma in 6 dogs; peripheral T-cell lymphoma, not otherwise specified, in 9 dogs). The OS of dogs diagnosed with epitheliotropic CTCL (141 days) was significantly shorter than that of dogs diagnosed with nonepitheliotropic CTCL (374 days). As clinical variables, the presence of neoplastic lymphocytes in peripheral blood, thrombocytopenia and initial chemotherapeutic response was related to prognosis. Our results demonstrated that histopathological subtype and several clinical variables were found to influence the prognosis of dogs with CTCL.

Abstract
We diagnosed epitheliotropic T-cell lymphoma of the forestomachs in 2 aged, half-sibling, zoo-managed bontebok (Damaliscus pygargus pygargus). One bontebok also had mesenteric lymph node and cutaneous involvement. Both animals had a history of chronic abdominal distension and diminished body condition that resulted in euthanasia. At autopsy, both animals had marked ruminal distension with diffusely blunted ruminal papillae and reticular crests. In case 1, there was an increased amount and particle length of the ruminoreticular fibrous material with scant fluid, and a 2-cm diameter focus of cutaneous crusting adjacent to a mammary teat. In case 2, the rumen and reticulum were fluid-distended with decreased fibrous material. Histologically in case 1, the rumen, reticulum, omasum, and skin had intraepithelial nests and sheets of neoplastic small lymphocytes; in case 2, the rumen and reticulum had a similar neoplastic cell population. Immunohistochemically, neoplastic lymphocytes were immunoreactive for CD3 and negative for CD20, confirming the diagnosis of epitheliotropic T-cell lymphoma.

Abstract
BACKGROUND Mycosis fungoides (MF) is an uncommon cutaneous neoplasm in dogs. Treatment options are limited. Total skin electron therapy (TSET) has been suggested as a possible therapy for canine MF. OBJECTIVE To describe the use of TSET as palliative treatment for MF in a dog. RESULTS An adult dog, previously diagnosed with nonepidermolytic ichthyosis, was presented with generalized erythroderma, alopecia and erosions. Histopathology revealed a densely cellular, well-demarcated, unencapsulated infiltrate extending from the epidermis to the mid-dermis compatible with MF. The infiltrate exhibited epitheliotropism multifocally for the epidermis, infundibula and adnexa. Due to a lack of response to chemotherapy, TSET was elected. Six megavoltage electrons were delivered using a 21EX Varian linear accelerator. A dose of 6 Gy was delivered to the skin surface and a 100 cm skin to surface distance was used for dog setup. The treatment time for the cranial half treatment was 3 h. The treatment was divided in two sessions (cranial and caudal halves of the body) 15 days apart. Clinical and histopathological complete remission was achieved and the dog was kept in remission with no additional treatments for 19 months before relapse and development of Sézary syndrome. CONCLUSION AND CLINICAL SIGNIFICANCE To the best of the authors' knowledge, this is the first case reporting the use of TSET for medically refractory canine MF with post treatment follow-up. This case suggests that the use of TSET may be an effective palliative treatment for canine MF.

Abstract
Oral mucocutaneous lymphoma is rare in dogs. Surgery and chemotherapy do not usually provide effective long-term control. The objective of this study was to retrospectively evaluate survival of dogs with localized oral lymphoma treated with radiation therapy. The medical database of three institutions was searched for dogs with diagnosis of oral lymphoma treated with radiotherapy. Dogs with evidence of systemic disease were excluded. Survival was calculated with the Kaplan-Meier method and prognostic variables analysed with log-rank test. Fourteen dogs were included in the study. Mean survival was 1129 days [95% confidence interval (CI) 711-1546] with median survival of 770 days. The overall response of radiotherapy was 67% (five complete and three partial responses). A survival advantage was seen in dogs with no evidence of lymph node metastasis (P = 0.002) and that achieved a complete response to radiation therapy (P = 0.013). Radiation therapy was a well-tolerated and effective treatment for localized oral lymphoma.

Abstract
Cutaneous epitheliotropic T-cell lymphoma in canine patients is a radiation sensitive tumor but total skin electron therapy is used only rarely. Our purpose was to evaluate dose distribution from a total skin electron therapy technique using 6MeV electron beams. The treatment was comprised of 12 fields, with the dog in lateral recumbency in a stride position at an extended distance from the source. Uniformity, flatness and symmetry were determined for each beam. The composite percent depth dose profile for all beams was measured in solid water phantoms and skin dose was determined on a canine cadaver using thermoluminescent dosimeters. The resulting d(max) of the composite beams was 1mm and dose variation over the skin was 6.8%, with the extremities having the most uneven dose distribution. Dimensions of the fields were adequate to obtain an effective treatment profile for the entire thickness of canine epidermis and the technique was feasible for clinical application. Individual tailoring of the protocol to deal with hot and cold spots may be necessary and set up will likely involve a significant time commitment for the therapy team.

Abstract
A 4-year-old female guinea pig was presented with pruritic, erythematous, hypotrichotic and scaling skin lesions, mainly involving the abdomen and the hindlegs. Clinical abnormalities were limited to the skin, and the guinea pig was otherwise healthy. The dermatological diagnostic work-up excluded ectoparasites, dermatophytosis and an endocrinopathy as differential diagnoses for the pruritus and hair loss. An allergic dermatitis was under investigation when the general and skin condition deteriorated. A neoplastic skin disorder was suspected, and skin biopsies revealed changes consistent with a cutaneous epitheliotropic T-cell lymphoma. Pautrier's microabscesses and immunophenotyped CD3(+) CD79(-) lymphocytes were identified. Owing to the deteriorating condition of the animal and the unknown but most likely poor prognosis of this disease, the guinea pig was euthanized. To the authors' knowledge, this is the first case report of cutaneous epitheliotropic T-cell lymphoma in the guinea pig with characteristic histopathological and immunohistochemical features.
