A letter to the editor is presented in response to the article about lymphomatoid granulomatosis, which appeared in the previous issue.

The article presents a case study of a 70-year-old man with Kikuchi disease (KD)-like syndrome presenting as a paraneoplastic syndrome. It says that the patient is presented with nodules and plaques on his trunk and face. It states that the patient has a histological diagnosis of metastatic adenocarcinoma of the lung. It adds that clinical and histological features revealed a case of KD.

Eosinophilic folliculitis (EF) is a descriptive histopathological term applied to a heterogeneous group of disorders. In EF, the characteristic histopathological features are eosinophilic spongiosis and pustulosis involving the infundibular region of the hair follicle. EF may be seen in association with bacterial and fungal infection, drug reactions and haematological disorders. However, in those conditions, the histopathological changes are rarely restricted to the infundibula but in most cases include a moderate to dense perifollicular or even diffuse dermal infiltrate of lymphocytes, or eosinophilic or neutrophilic granulocytes. We present two cases of EF after mini-allogeneic bone-marrow transplantation (BMT) in order to highlight this rare and perhaps under-recognized clinical association. [ABSTRACT FROM AUTHOR]
