Overview
The Anaplastic large cell lymphoma ALK-positive (Anaplastic Llymphoma Kinase) consist of CD30-positive T-cells with abundant cytoplasm, a pleomorphic nucleus (horseshoe-shaped nucleus) and a eosinophilic paranuclear region[1]. This ALK-positive lymphoma has a translocation in the ALK gene [T(2;5)(p23;q35)], which will in turn, express the ALK protein[2].
Historical Perspective
Classification
Pathophysiology
ALCL morphologic features are variable, which allowed to classify this entity into five morphologic patterns[2]:
- "Common" pattern: Its the most common morphologic variant (75%)[3]. Cytoplasm may be basophilic or eosinophilic and the cell might have many nuclei with dispersed or clumped chromatin. In large cells, nucleoli tends to be more prominent. Given that the lymphomatous cells grow in the lymph node's sinuses, it may resemble a metastatic tumor.
- Lymphohistiocytic pattern (10%): histiocytes with acidophilic cytoplasm and a perinuclear clear area, which represents the Golgi apparatus. This cells have eccentric nuclei with condensed chromatin[4]. Lymphomatous cells tend tu cluster around the perivascular area, evidenced by immunostaining with CD30 and ALK antibodies[2].
- Hodgkin's like pattern (3.3%): Morphological characteristics reassemble Hodgkin's lymphoma, variant nodular sclerosis[5]. Predominates in female patients over male patients.
- Small cell pattern (8.3%): Present nuclear irregularity and perivascular/intravascular distribution[6]. Occasionally, this lymphomatous cells have pale cytoplasm with a central nucleus ("fried egg cell")[2].
- Giant cell pattern (3.3%)
One single patient may present more than one morphologic pattern in the same or progressive biopsies[1].
Causes
Differential Diagnosis
Epidemiology and Demographics
This entity affects primarily young, male patients[7] and accounts for 3% of all NHL, 40% of all large cell lymphomas[8] and 10%-20% of childhood lymphomas, although it is particularly incident in patients between 10 and 29 years[9].
A more recent study evaluated 1,320 cases of peripheral T-cell lymphomas and NK cell lymphomas between 1990 and 2002 in 22 different centers, concluding that the ALK-Positive ALCL is the fifth most incident (6.6% of total patients)[10], although in the United states, it's the most frequent type of peripheral T-cell lymphoma.
Risk Factors
Natural History, Complications and Prognosis
Diagnosis
History and Symptoms
Most adult patients present with painless lymphadenopathy. Although retroperitoneal and peripheral[11] lymphadenopathyis very common, other possible locations include the gastrointestinal tract, breast[12], spleen[13], liver[14], bone[14] and respiratory tract[15].
Common symptoms include typical B symptoms[16](Fever, weight loss and night sweats).
