Extracutaneous dissemination may occur, especially to regional lymph nodes. Prognosis is good and does not depend on lymphatic invasion.

granees The present study reports the case of a year-old-woman presenting Primary cutaneous anaplastic large-cell lymphoma with multifocal lesions. The pacient evolved with pulmonary involvement 7 years later. She showed a good response to the treatment with low-dose methotrexate prescribed weekly.

Apresentou boa resposta ao tratamento com metotrexato em baixas doses semanais. The primary cutaneous anaplastic large cell lymphoma PCALCL is a non-Hodgkin lymphoma NHL of cutaneous T-cell presentation, without systemic involvement at the time of the diagnosis and in the next six months.

Most patients present with solitary or localized nodules, papules or plaques. Ulceration may be present or not. The lesions usually occur on the trunk, face, extremities and buttocks and are usually asymptomatic.

The main differential diagnoses include lymphomatoid papulosis LP and systemic anaplastic large cell lymphoma with cutaneous involvement.

To distinguish PCALCL and LP, longitudinal observation is often necessary as the histopathological differentiation between the two conditions is difficult. Although more diffuse, they are self-limited and do not progress with time. Regarding systemic lymphoma, it is more common in young men, under 35 years old, presenting with disease in stage III or IV with lymphadenopathy, B symptoms and a short and progressive coursebesides presenting translocation t 2. A woman, aged 57, female, from Campina Grande-PB, has had skin lesions since The lesions began as eczema located in upper and lower limbs that have evolved to a widespread scaly and quite pruritic rash with papules and nodules which ulcerated and spontaneously regressed, leaving permanent hypochromic stains Figures 1 and 2.

She underwent three skin biopsies inand ; the first two were not conclusive. The lesion biopsy performed ceelulas showed infiltration of atypical lymphoid cells of medium and large sizes in the superficial and reticular dermis and in the subcutaneous tissue with significant eosinophilia Figure 3 suggesting the creation of a immunohistochemical panel for cancer that was positive for CD30CD3 and CD15 markers and negative for Ki67 and ALK.

As for the diagnosis, tomography of the chest showed several nodules scattered throughout the parenchyma of both lungs Figure 4. Treatment was initiated with methotrexate in weekly doses and achieved good clinical response.

In the literature, grandss type of lymphoma affects more frequently males than females with a ratio of 1. The lesions improved spontaneously as well as regressed, which is consistent with recent literature.

The most common form of systemic involvement is regional lymph nodes, but the patient had an atypical systemic involvement on lung, after seven years of evolution. This case report shows the importance of defining the diagnosis to individualize treatment, avoiding aggressive conduct for treating a disease with good prognosis, despite the exuberance of clinical manifestation. Regardless of good prognosis, it is necessary to closely monitor these patients because of the potential risk of dissemination or extracutaneous spread, besides recurrence of the disease or even development of other malignancies, such as mycosis fungoides, Hodgkin or non-Hodgkin lymphomas.
