A number of non-haematolymphoid proliferations cause lymphadenopathy that may clinically simulate malignant lymphoma. The commonest of these are metastatic anaplastic carcinomas and melanomas, which may mimic large cell lymphomas and occasionally Hodgkin lymphoma. Carcinomas usually have a more cohesive growth pattern than malignant lymphomas and, in their early stages, may be predominantly sinusoidal in their distribution. However, sinusoidal distribution is also seen in some cases of anaplastic large cell lymphoma and diffuse large B-cell lymphomas.
