Primary cutaneous eosinophil-rich anaplastic large cell lymphoma: report of an unusual case and literature review

BACKGROUND: Cutaneous, neutrophil-rich anaplastic large cell lymphoma (ALCL) is an uncommon variant of ALCL that may be confused with inflammatory dermatoses. OBJECTIVE AND METHODS: We describe an eosinophil-rich variant of ALCL occurring on the left ear without systemic involvement. The lesion had inflammatory characteristics, which led initially to a histological diagnosis of an inflammatory process. Two months later, a second biopsy diagnosed eosinophil-rich variant of ALCL. The patient underwent radiation therapy, but due to the extensive deformation and mutilation of the ear, the patient elected to have the ear amputated. We discuss the clinicopathological findings and the differential diagnosis CONCLUSIONS: To the best of our knowledge, the occurrence of a cutaneous, eosinophil-rich variant of ALCL has not been previously reported. It is important to alert pathologists to this variant of ALCL so that this possibility may be considered in the early differential diagnosis of inflammatory cutaneous conditions.     

Primary cutaneous anaplastic CD30+ large cell lymphoma

Primary cutaneous anaplastic CD30+ large cell lymphoma (PCALCL) is part of the spectrum of primary cutaneous CD30+ lymphoproliferative disorders together with lymphomatoid papulosis. It affects mainly elderly patients and presents as skin nodules that tend to ulcerate. Histological and immunohistochemical study show the expression of CD30 antigen in more than 75 % of neoplastic cells. Currently it is considered a low grade lymphoma with favourable prognosis and good response to treatments such as local radiotherapy, methotrexate or surgery. We report a 93-year-old patient with ulcerated nodules in her right leg. Histological and immunohistochemical study confirmed the diagnosis of PCALCL, of non-B, non-T origin. The patient was treated with local radiotherapy with progressive resolution of skin nodules and absence of relapse at 6 months follow-up.

Primary cutaneous multifocal CD30+ anaplastic large cell lymphoma

A 45-year-old male presented with asymptomatic tumors all over the body. The tumors showed no signs of ulceration or regression. There were generalized, nontender, firm to hard enlarged lymph nodes without hepatosplenomegaly. Biopsy and immunophenotyping revealed CD 30+ anaplastic primary cutaneous large cell lymphoma. Primary cutaneous anaplastic large cell lymphoma is characterized by single or grouped reddish-brown tumor nodules, which frequently tend to ulcerate. Secondary involvement of lymph nodes is seen in only 25%. The lesions responded dramatically to chemotherapy, but recurred.

Diffuse large cell non-Hodgkin's lymphoma, CD30+, T-cell phenotype

A 63-year-old Chinese man presented with an eczematous dermatitis that progressed into a multifocal nodular eruption. Histopathologic examination demonstrated a nodular and diffuse infiltrate in the reticular dermis, which was composed of lymphocytes, macrophages with granulomatous inflammation, and numerous eosinophils. Reactive lymphoid follicles with germinal centers also were present. Immunohistochemistry showed CD30 and LCA. ALK-1 and CD20 were negative. A diagnosis of CD30+ cutaneous T-cell lymphoma was made, and the patient is currently undergoing staging of his disease. Treatment options include excision of nodules, radiation therapy, and systemic chemotherapy.     

Primary cutaneous CD30-positive large cell lymphoma

Primary cutaneous CD30-positive large cell lymphoma is a recently described entity, recognized by immunohistochemical criteria. Spontaneous regression may occur and although relapses are frequent, most patients have a favourable prognosis. We describe a 83-year-old woman with a large ulcerated tumour on her right forearm, with 2 months evolution. Histological and immunohistochemical examination revealed a CD30-positive large cell lymphoma. Systemic involvement was not detected. The tumour regressed spontaneously. Cutaneous relapses occurred one year later, all with spontaneous regression. After a 2-year follow-up period, the patient is well, without concurrent extracutaneous disease. This case is in keeping with other reports of spontaneous regression and favourable outcome of this type of cutaneous lymphoma.

Primary cutaneous CD30-positive anaplastic large cell lymphoma. Report of 27 cases

The clinical, morphological and immunohistochemical features of 27 patients with anaplastic large cell lymphoma (ALCL) of CD30-positivc type, with cutaneous lesions as the sole initial clinical manifestation, were analyzed. The neoplasm presented as solitary or multiple, usually ulcerated skin lesions, affecting predominantly elderly patients (median age: 67 years) with a male preponderance (male to female ratio of 6:1). In most patients, there was an excellent response to chemotherapy. The cardinal histological features included diffuse dermal and sub-cutaneous infiltration by large, anaplastic tumor cells, all or nearly all of which showed diffuse, strong membrane staining and frequently a paranuclear, dot-like reaction with the CD30 marker (Ber-H2). Epidermal ulceration, pseudo-epitheliomatous hyperplasia and dermal vascular proliferation were also ob-served.
