Maxillary chloroma: a myeloid leukaemic deposit.

A chloroma is described in the left quadrant of the maxilla in a 4-year-old girl. This patient had previously completed a course of chemotherapy for acute myeloid leukaemia, but had been off all drug therapy and in remission for 1 year prior to presentation. Chloroma is a well recognised, if uncommon, mode of presentation of acute myeloblastic leukaemia and a previous case of chloroma occurring in the mandibular gingival tissues has been reported (Reichart et al., 1984). An unusual feature in the present case is the appearance of the chloroma as a form of leukaemic relapse and as a solitary deposit which is itself uncommon in acute myeloblastic leukaemia. It is suggested that this chloroma was a leukaemic deposit which had spread from within the maxillary antrum or the tissues adjacent to the meninges.
