Kort sagt

Cutaneous lymphoma is an uncommon but serious skin cancer in dogs and cats where abnormal white blood cells accumulate in the skin, causing persistent redness, scaling, hair loss, or lumps that can easily be mistaken for chronic allergies.

A golden retriever with visible hair loss and red, flaky skin on its side.
Cutaneous lymphoma can cause widespread hair loss, redness, and scaling that mimics severe allergies.

TL;DR. Ovanlig men allvarlig hudcancer: onormala lymfocyter i huden med rodnad, fjällning, håravfall eller knutor; ofta förväxlad med allergi.

Utbrett håravfall, rodnad och fjällning kan imitera allergier.

Vad är det?

Maligna lymfocyter i huden. Epiteliotróp (ofta T-celler, epidermis/mun) vs icke-epiteliotróp (B/T, dermala/subkutana knutor).

"Nonepitheliotropic lymphoma is a malignant neoplasm that may arise from B or T lymphocytes. It is uncommon in dogs and cats, with highest incidence in older animals. Usually, nonepitheliotropic lymphoma appears as multiple, firm,"

Orsaker och riskfaktorer

Orsak oklar. Ålder ökar risken. Hundraser: Boxers, Scottish Terriers, Golden Retrievers, Rottweilers.

Tecken

  • Vanliga: klåda, fjällning, plack/knutor, erytem, alopeci
  • Ibland: trampdynshyperkeratos, orala sår, mukokutan depigmentering, lymfadenomegali

A cat's muzzle showing loss of pigment and small ulcerations around the lips.
Mukokutan depigmentering och sår möjliga.

Diagnostik

FNA begränsad; biopsi/histopatologi guldstandard. Staging: blod, ultraljud, thoraxröntgen, lymfkörtelf-FNA.

"Distinguishing these requires a biopsy sample to assess the tissue distribution of lymphocytes in relation to the epidermis, and this cannot be done with cytological samples."

Behandling

Systemisk: COP Chemotherapy Protocol. Stöd: antibiotika/antimykotika, medicinska bad, analgesi.

Prognos

Långsamt progressiv, bot sällsynt. Epiteliotróp ofta långsammare; icke-epiteliotróp ofta aggressivare/systemisk tidigare.

Prevention

Ingen säker prevention. Tidig biopsi vid refraktär dermatos.

När kontakta veterinär

Akut: kollaps; ihållande kräkning/diarré; spänd buk; andnöd.

För vissa raser

Boxer, Scottish Terrier, Golden Retriever, Rottweiler: utred tidigt kroniska hudförändringar och knutor, inte bara som allergi.
