Hereditary Progressive Mucinous Histiocytosis: First Report in a Male PatientAbstract:
Progressive mucinous histiocytosis is a very rare, benign,
non-Langerhans’ cell histiocytosis limited to the skin. In total ten
patients (all women) in four families and three sporadic cases have been
reported. We report here the first published case of a male patient
with progressive mucinous histiocytosis. The multiple red papules on the
scalp and forearms were asymptomatic and had slowly increased over
approximately the past 20 years. The patient’s mother had similar
lesions. Histological examination revealed nodules in the dermis with
histiocytes and mucin deposition. The histiocytes stained positively
with CD31 and negative with CD34, CAM 5.2, PGM-1 and factor XIIIa.
Ultrastructurally, the histiocytes show ed numerous circular myelin
bodies and zebra bodies reminiscent of those seen in lysosomal storage
diseases. The genetic transmission of hereditary progressive mucinous
histiocytosis remains unclear; we assume an autosomal dominant
transmission with some hormonal factor that makes hereditary progressive
mucinous histiocytosis more likely in women. Authors:
