(LyP) is a rare cutaneous condition characterized by chronic, recurrent, and self-regressing papulonodular skin eruptions.
Other [CD30.sup.+] cutaneous T-cell lymphoproliferative disorders (CTCLs) include primary cutaneous anaplastic large cell lymphoma (C-ALCL) and lymphomatoid papulosis
(LyP), which present as a range of cutaneous nodules that in the case of LyP self-resolve.
CD30+ cutaneous lymphoproliferative disorders: the Stanford experience in lymphomatoid papulosis
and primary cutaneous anaplastic large cell lymphoma.
"There are reports about T-cell receptor clonality in PL lesions and its similarity and association with lymphomatoid papulosis
and mycosis fungoides, and the presence of CD30-positive and CD7 deletions," she said.
(LyP) is a benign papulonodular skin eruption with histologic features of malignant lymphoma.

. FDG PET may have poor sensitivity for cutaneous lesions in these disorders and have a higher rate of false-negatives in detecting involved lymph nodes.

Anaplastic large cell lymphoma and lymphomatoid papulosis
are CD30-positive lymphoproliferative disorders that have reported cases being associated with epidermal hyperplasia .
All patients were suffering from relapsed CD30-positive cutaneous lymphoproliferative disorders, including lymphomatoid papulosis
(LyP), primary cutaneous anaplastic large cell lymphoma (pcALCL) or mycosis fungoides (MF).
CD30+ lympho-proliferative disorders include a wide spectrum of disease with lymphomatoid papulosis
at the benign end of the spectrum and cutaneous CD30+ anaplastic large-cell lymphoma (ALCL) at the malignant end.1 Many described borderline lesions are somewhere in between.
