WHO Classification of Disease
| Structure | Disease |
|---|---|
| Book | Haematolymphoid Tumours (5th ed.) |
| Category | T-cell and NK-cell lymphoid proliferations and lymphomas |
| Family | Mature T-cell and NK-cell neoplasms |
| Type | Primary cutaneous T-cell lymphoid proliferations and lymphomas |
| Subtype(s) | Primary cutaneous CD30-positive T-cell lymphoproliferative disorder: Primary cutaneous anaplastic large cell lymphoma |
Definition / Description of Disease
- Primary cutaneous anaplastic large cell lymphoma (C-ALCL) is a form of cutaneous T-cell lymphoma with majority (>75%) of tumor cells expressing CD30.
- CD30+ LPDs are a part of a spectrum of diseases with overlapping features and are associated with an excellent prognosis. The group includes lymphomatoid papulosis (LyP) and C-ALCL, which are distinguished by clinical features and disease course.
- C-ALCL is a distinct entity from systemic anaplastic large cell lymphoma (ALCL), which can have cutaneous involvement.
- Diagnosis must exclude large cell transformation of mycosis fungoides, which can express CD30.
editUnassigned ReferencesThe following referenees were placed in the header. Please place them into the appropriate locations in the text.
Synonyms / Terminology
- Primary Cutaneous CD30-positive T-cell lymphoproliferative disorder
Epidemiology / Prevalence
- Second most common type of cutaneous T-cell lymphoma
- Median age: 60 years. Cases have been reported in children.
- Male:Female 2-3:1
- Disease-specific 5-year survival rate 95%
editUnassigned ReferencesThe following referenees were placed in the header. Please place them into the appropriate locations in the text.
Clinical Features
Put your text here and fill in the table (Instruction: Can include references in the table. Do not delete table.)
| Signs and Symptoms | EXAMPLE: Asymptomatic (incidental finding on complete blood counts)
EXAMPLE: B-symptoms (weight loss, fever, night sweats) EXAMPLE: Fatigue EXAMPLE: Lymphadenopathy (uncommon) |
| Laboratory Findings | EXAMPLE: Cytopenias
EXAMPLE: Lymphocytosis (low level) |
editv4:Clinical FeaturesThe content below was from the old template. Please incorporate above.
- Solitary or localized nodules or tumors, with frequent ulceration. Multifocal lesions are seen in 20% of patients.
- Lesions may regress, either partially or completely, but cutaneous relapse is common.
- Extracutaneous dissemination is seen in 10-15% of cases, most cases involving regional lymph nodes.
- Associated with excellent prognosis, even in those with regional lymph node involvement or multifocal skin lesions.
- Anaplastic morphology does not impact disease course or prognosis.
- Distinguishing from LyP is important for therapy, as surgical excision and radiotherapy are first-line treatments in patients with C-ALCL.
editUnassigned ReferencesThe following referenees were placed in the header. Please place them into the appropriate locations in the text.
Sites of Involvement
- Limited to cutaneous sites, most frequently affecting the trunk, face, and extremities.
editUnassigned ReferencesThe following referenees were placed in the header. Please place them into the appropriate locations in the text.
Morphologic Features
- Sheets or nodular dermal infiltrate of large pleomorphic, anaplastic, or immunoblastic cells
- Irregularly shaped nuclei
- Abundant, pale to eosinophilic, cytoplasm
- Reactive lymphocytes in the periphery
- Ulcerated lesions may resemble lymphomatoid papulosis with increased inflammatory infiltrate composed of T-cells, histiocytes, eosinophils, and neutrophils, with fewer CD30+ cells.
- In cases harboring DUSP22-IRF4 translocations, CD30+ cells commonly display biphasic morphology - small, cerebriform lymphocytes within the epidermis and large transformed cells in dermis.
editUnassigned ReferencesThe following referenees were placed in the header. Please place them into the appropriate locations in the text.
Immunophenotype
| Finding | Marker |
|---|---|
| Positive (activated T-cell markers)* | CD4, CD30 (diagnosis requires >75% expression of tumor cells) |
| Variable (pan T-cell markers) | CD2, CD3, CD5 |
| Positive | Cytotoxic proteins†: Granzyme B, TIA1, perforin
CD15 (40%), IRF4/MUM1, CLA (cutaneous lymphocyte antigen) |
| Negative | EMA‡, ALK‡, PAX5, EBV, CD56 (rare cases with coexpression) |
*Some cases may have a T-cell phenotype of CD4-/CD8+ or CD4+/CD8+ or null-cell phenotype.
†Cases with DUSP22-IRF4 rearrangement tend to express
‡EMA and ALK are typically positive in systemic ALCL, however there are rare cases of ALK+ primary C-ALCL.

- Rearrangements of DUSP22-IRF4 locus on chromosome 6p25.3 are found in 25% of primary C-ALCL and in rare cases of LyP and transformed mycosis fungoides. The rearrangements have not found in systemic ALCL or other T-cell LPDs.[4]
- TYK2 (19p13) rearrangements in 15% of CD30+ lymphoproliferative disorders, with recurrent NPM1-TYK2 fusions reported in primary C-ALCL and LyP.[5]
