  Parapsoriasis is a papulosquamous disorder of unknown etiology with remissions and exacerbations.  Aim: We studied clinical and histopathological features of parapsoriasis. Methods: This is a prospective, study of patients clinically diagnosed as parapsoriasis and confirmed by histopathology.  Results: There were 28 (15 males and 13 females) cases of parapsoriasis in the study period. The maximum number of cases, 10 (35.70%) were in their third decade of life. Pityriasis lichenoides chronica was diagnosed in 24 cases (85.71%), pityriasis lichenoides et varioliformis acuta (PLEVA) in 2 cases (7.14 %) and plaque parapsoriasis in 2 cases (7.14%). Histopathologically, parakeratosis, basal cell vacuolation, and perivascular infiltrate was seen. One case of plaque type parapsoriasis showed  epidermoptropism with atypical cells suggestive of mycosis fungoides.  Conclusion: Pityriasis lichenoides chronica is a relatively common disease amongst parapsoriasis. Histopathology is a must to rule out early mycosis fungoides in plaque type of parapsoriasis
