Cutaneous extramedullary hematopoiesis is a rare manifestation of chronic myeloproliferative processes, mainly chronic idiopathic myelofibrosis. In adults, it manifests as macules, papules, nodules, and ulcers on the trunk. The lesions usually appear soon after diagnosis and the possibility of a relationship between splenectomy and the appearance of extramedullary foci of hematopoiesis is still debated. Diagnosis is based on histopathology showing an infiltrate with different combinations of myeloid and erythroid cell precursors and megakaryocytes. Symptomatic treatment is provided alongside treatment of the underlying disease. We report a new case associated with chronic idiopathic myelofibrosis in which foci of cutaneous extramedullary hematopoiesis were observed 9 years after initial diagnosis. The lesions were progressive and the patient went on to develop acute myeloid leukemia.

Cutaneous manifestations of multiple myeloma are rare but, as with other extramedullary manifestations, carry a worse prognosis. We present the case of a 65-year-old man with immunoglobulin G κ multiple myeloma and prior autologous stem cell transplant. On subsequent therapy, he presented with multiple new cutaneous and subcutaneous left hip masses.

We describe a case of a 24 year old female who came with complaint of bilateral tinnitus, profound hearing loss, and weakness in both lower limbs which on imaging work up showed unilateral acoustic schwannoma, and spinal extramedullary intradural lesions at D8-D9 level giving the classical features of neurofibromatosis II along with cafe au lait spots, axillary freckling, cutaneous neurofibromas, which are unique to NF1. The purpose of this report is to discuss the study of a patient with classical features of both NF-I and NF-II, emphasizing the need for surveillance regarding sporadic mutations seen in NF I AND NF II genes, as well as genetic mosaicism to be kept in mind when diagnosing such patients.
