Fatal outcome of deep-penetrating lower limb primary cutaneous anaplastic large cell lymphomas in two immunocompromised patients.
The occurrence of primary cutaneous anaplastic large cell lymphoma (PCALCL) in immunocompromised patients is rare. Only 11 cases have been reported to date, all of them in organ transplant recipients and none in patient with idiopathic CD4+ T-cell lymphocytopaenia. We describe here the original clinical pattern of deep, fascia and muscle-penetrating PCALCL of the lower limb in two immunocompromised patients, one in a renal transplant recipient, the other in a patient with idiopathic CD4+ T-cell lymphocytopaenia. Both patients experienced a negative outcome, contrasting with the usually indolent course of PCALCL in immunocompetent patients, since both died of complications related to the lymphoma 30 and 13 months later, respectively. The unusual clinical aggressiveness of these two cases of PCALCL suggests that, in this peculiar subset with a deep structures involvement hallmark, a worse prognosis could be expected, especially in immunocompromised patients. This information should be taken into consideration when making therapeutic choices.
