Diagnosis Lues maligna

lues maligna (malignant syphilis) severe form of secondary syphilis spontaneous resolution increasing the incidence for the past few decades following the rise in prevalence of HIV

Diagnosis criteria for lues maligna compatible gross and microscopic morphology high titer of antibodies in the serologic test of syphilis excellent response to antibiotic therapy and Jarisch Herxheimer reaction following treatment. Text Fisher DA, et al. Lues maligna. Arch Dermatol 1969; 99: 70–73.

Clinical cutaneous: slightly painful erythematous-violaceous papules and nodules with centrally ulcerate and cover by brown crusts area: head, neck, trunk, limbs +/- palm, oral mucosa non cutaneous: lymphadenopathy hepatosplenomegaly low grade fever, malaise risk factor HIV, DM alcoholic patient mulnutrition

Histology hematoxylin and eosin stain; predominant plasma cell Warthin-Starry, modified Starry or Steiner stains may help to identify spirochete

Treatment Benzathine penicillin 2.4 million unit intramuscular single dose closely observed for Jarisch Herxheimer reactions follow up anti HIV

Treatment Benzathine penicillin 2.4 million unit intramuscular single dose no Jarisch Herxheimer reactions RPR 1:32  1:8 follow up anti HIV
