الملخص EN

Composite lymphoma is the presence of different morphological types of lymphoma in a single lymph node at the time of clinical presentation.

It is a rare type of lymphoid neoplasm, present in lymphoid tissue.

This paper is presenting four rare cases of composite lymphoma identified in our clinical practice.

Three of the cases were female: one with inguinal mass, second with cervical lymph nodes enlargement, and the third with enlarged tonsils.

The fourth case was a male presented with enlarged tonsils.

The patients' ages ranged between 40-54 years.

Histopathological examinations and immunohistochemistry features proved the diagnosis of composite lymphoma.

Two of the cases presented with a rare association of Hodgkin's and non-Hodgkin's lymphoma The third case represents two different types of non-Hodgkin's lymphoma, and the fourth case represents a rare association of high grade non-Hodgkin's lymphoma and low grade follicular center cell lymphoma.

The authors discuss, in detail, these four cases and review the literature of similar association.
