A rare subtype of mycosis fungoides (MF) known as pityriasis lichenoides-like mycosis fungoides (PL-like MF) manifests as recurrent crops of erythematous scaly papules with the histological findings of MF. We report a 64-year-old male with recurrent crops of psoriasiform papules with mild scales on his trunk and extremities. Skin biopsy results were consistent with CD8+ cutaneous T-cell lymphoma (CTCL). Our patient had clinical features of pityriasis lichenoides and histological findings consistent with CD8+ MF. A differential diagnosis of PL, lymphomatoid papulosis (LyP), and PL-like MF was considered. Counseling patients with CD8+ cutaneous T-cell lymphoma can be challenging, as there is an aggressive variant named primary cutaneous aggressive epidermotropic CD8+ CTCL. However, with the ability to recognize PL-like MF, a rare indolent type of CD8+ CTCL, physicians can counsel patients appropriately.

Review
Pityriasis lichenoides et varioliformis acuta (PLEVA), or Mucha-Habermann disease (MHD), is a cutaneous disorder evident with crops of erythematous macules and papules, usually on the trunk and flexural areas of the extremities. Its etiology remains unknown. PLEVA is speculated to be an inflammatory reaction triggered by certain infectious agents, an inflammatory response secondary to T-cell dyscrasia, or an immune complex-mediated hypersensitivity. Histologic examination of a skin biopsy specimen is the standard for the identification of PLEVA, but definitive diagnosis may be difficult. Apart from the febrile ulcerative variant, which may be fatal, PLEVA tends to be self-limited in its course. Treatment is targeted mainly at the symptomatic relief of pruritus.

Review
PURPOSE OF REVIEW
The purpose of this review is to educate the reader about two cutaneous lymphoproliferative diseases in childhood: pityriasis lichenoides and cutaneous T-cell lymphoma. Pityriasis lichenoides has traditionally been divided into acute and chronic subtypes. The two forms of the disease, however, are best thought of as two ends of a benign lymphoproliferative spectrum. Cutaneous T-cell lymphoma is a rare but underrecognized cutaneous malignancy in children. Early stage disease and hypopigmented presentation are characteristic of pediatric cutaneous T-cell lymphoma. The optimal investigation and treatment plans are still controversial.
RECENT FINDINGS
This article will summarize recent articles on pityriasis lichenoides and pediatric cutaneous T-cell lymphoma, including recent findings from an international registry of pediatric cutaneous T-cell lymphoma.
SUMMARY
After reading this review, the reader should be able to recognize the clinical presentation of pityriasis lichenoides, to understand the overlap between its acute and chronic forms, and to recognize its relationship with cutaneous T-cell lymphoma. In addition, the reader will appreciate the challenges in diagnosing and treating pediatric cutaneous T-cell lymphoma.
