Pityriasis lichenoides is a rare inflammatory dermatosis occurring in young subjects. It evolves into rashes on the trunk and the limbs which regress spontaneously. We here report a particular case of pityriasis lichenoides whose diagnosis was adjusted due to the scar appearance of the lesions. The patient was treated with cyclin and phototherapy, with a favorable outcome.

Review
Paraneoplastic dermatoses are non-neoplastic skin disorders which occur in the context of an underlying malignant neoplasm. The classic paraneoplastic dermatoses are mostly associated with solid internal malignancies. They only rarely occur in the context of nodal or primary cutaneous lymphomas. Apart from these classic paraneoplastic dermatoses, there are additional skin disorders reported to occur in close association with haematological and lymphoproliferative disorders which can thus be regarded as paraneoplastic manifestations. We report for the first time two patients with pityriasis lichenoides et varioliformis acuta in association with mycosis fungoides. In addition, we review the literature on paraneoplastic dermatoses of the skin which have been described in patients with leukaemias and primary cutaneous lymphomas.

Review
A review of the literature concerning the pityriasis lichenoides and the study of 34 personal cases show that three main clinical patterns are found in pityriasis lichenoides: maculo-papular, leukomelanodermal, necrotic. The course is very variable: rarely seven weeks, more often seven months and sometimes seven years. The disease is issued from an angiitis including a mostly lymphocytic infiltration. The epidermis is secondarily invaded by inflammatory cells and shows focal parakeratosis. There is no specific immunologic disorder: immunohistopathologic study is generally normal (rarely IgM or C3 deposits); no circulating immune complex is found. Some patients improved with dapsone or photochemotherapy.

Review
Pityriasis lichenoides et varioliformis acuta and pityriasis lichenoides chronica are the 2 main subtypes of pityriasis lichenoides. They represent the acute and chronic forms of the disease; both may have clonal T cells. Several treatment modalities are used, but it has been difficult to determine efficacy because of the possibility of spontaneous remission. Cutaneous CD30+Â lymphoproliferative disorders constitute many cutaneous T-cell lymphomas and comprise lymphomatoid papulosis and primary cutaneous anaplastic large cell lymphoma (ALCL). Both have an excellent prognosis. Lymphomatoid papulosis often only requires observation or treatment of symptoms. First-line therapies for primary cutaneous ALCL are surgical excision or radiotherapy.
