Yes, lymphocytoma cutis and lymphoma cutis are different conditions that affect the skin.

Lymphocytoma cutis is a non-cancerous (benign) condition and lymphoma cutis is a type of cancer. Sometimes the conditions can look very similar. So it is always important for doctors to take a sample from the affected area of skin (a biopsy) to be sure of the diagnosis.

Lymphocytoma cutis is an uncommon skin reaction. It can be caused by infection, tattoos, ear piercing, vaccinations, anything that causes damage to an area of skin. Sometimes it isn't clear what has caused it. It may clear up on its own or may need treatment.

Lymphoma cutis is a type of cancer called non-Hodgkin lymphoma (NHL). There are different types of NHL that can affect the skin. Lymphoma cutis is a general term to describe any type of NHL in the skin. It may be treated with a treatment directed at the skin or with a treatment that works throughout the body.
