Lymphomatoid Papulosis - Causes, Symptoms & Treatment

Lymphomatoid papulosis is a rare skin disorder. It is characterised by crops of self healing skin lesions. It is characterized by recurrent crops of pruritic papules at different stages of development that predominantly arise on the trunk and limbs. The papules heal spontaneously over 1-2 months, usually leaving slightly depressed oval scars. Lesions contain unusual cells that are similar to those found in some lymphomas (cancers of the lymphatic system).

Most cases of lymphomatoid papulosis are benign, 10-20% of patients may have an associated lymphoma. This may be cutaneous T-cell lymphoma or an internal form of the disease. There are also CD 30+ cutaneous T cell lymphomas presenting clinically with solitary or few tumours or ulcers but with histologic features of lymphomatoid papulosis. It is likely the CD 30+ lymphoproliferative disorders represent a clinical and histologic spectrum with lymphomatoid papulosis at one end and T cell lymphoma on the other, with borderline cases in between. Genetic instability of tumor cells may lead to altered expression of apoptotic proteins and immune-regulatory molecules, such as transforming growth factor-beta.

It may occur anywhere on the body but most often affect the chest, stomach, back, arms and legs. Lesions spontaneously heal with or without scarring within 2-8 weeks of appearing. CD30 signaling is known to have an effect on the growth and survival of lymphoid cells. Papules appear in crops and may be mildly itchy. They may develop into blood or pus-filled blisters that break and form a crusty sore before healing completely. JunB is a potential target for experimental therapy in patients with these tumors.LyP may develop at any age, but the peak incidence occurs in the fifth decade. Allelic form of the CD30 promoter microsatellite repressive element was associated with the development of LyP, and the 30M362 allelic form was associated with progression to other CD30 + lymphomas in LyP patients. JunB, part of the AP-1 transcription factor complex involved in cell proliferation and apoptosis, in virtually all CD30 + lymphomas.

Treatment of Lymphomatoid Papulosis

Common Treatment of Lymphomatoid Papulosis

• Topical agents include glucocorticoids and carmustine (BCNU).
• Electron-beam irradiation has been employed as well.
• PUVA may control the disease but does not affect the long-term prognosis.
• Tetracyclines, sulfones, systemic glucocorticoids, and even acyclovir have been reported as effective by some researchers.
• Cortisone ointments will sometimes help.
• Ultraviolet light treatment will help control lymphomatoid papulosis.
• Methotrexate is sometimes used to treat lymphomatoid papulosis.
