UNUSUAL MANIFESTATION OF MALIGNANT RETICULOSIS OF SKIN - CUTANEOUS LESION SIMULATING PARAPSORIASIS GUTTATA

Two cases were presented which were thought to be a variant of malignant reticulosis of the skin. Both cases revealed papular eruption which clinically resembled parapsoriasis guttata. Each of the papular eruptions disappeared spontaneously despite the fact that their histopathology showed the presence of infiltration consisting of large atypical reticulum cells. One of the cases developed lympho- matous skin tumors seven years after the onset of the preceding papular eruption and died due to invasion of the lymph nodes and internal organs. From the clinicopathological studies, this peculiar eruption is thought to be a manifestation resulting from interplay between the neoplastic induction and host. © 1969 S. Karger AG, Basel.
