Haematolymphoid Tumours (5th ed.)
 | This page is under construction |
(General Instructions – The main focus of these pages is the clinically significant genetic alterations in each disease type. Use HUGO-approved gene names and symbols (italicized when appropriate), HGVS-based nomenclature for variants, as well as generic names of drugs and testing platforms or assays if applicable. Please complete tables whenever possible and do not delete them (add N/A if not applicable in the table and delete the examples). Please do not delete or alter the section headings. The use of bullet points alongside short blocks of text rather than only large paragraphs is encouraged. Additional instructions below in italicized blue text should not be included in the final page content.

|---|---|
| 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 | Primary cutaneous acral CD8-positive T-cell lymphoproliferative disorder |
Cancer Sub-Classification / Subtype
None
Definition / Description of Disease
Primary cutaneous acral CD8-positive T-cell lymphoproliferative disorder is a rare type of lymphoproliferative disorder characterized by slow-growing papules and nodules primarily affecting acral sites such as the ears with benign clinical course. [1]
Synonyms / Terminology
None
Epidemiology / Prevalence
Uncommon disease accounting for < 1% of all primary cutaneous lymphomas. The disease predominates in male with M:F ratio of 2:1. The median age is 56 years. No pediatric cases are reported till now.[2]
Clinical Features
Put your text here and fill in the table (Instruction: Can include references in the table)
| Signs and Symptoms | Cutaneous, slowly progressive papule or nodule |
| Laboratory Findings | None |
Sites of Involvement
Ears (the commonest), nose, and feet.
Rare sites: Leg, trunk, genital, and eyelid.[1][4] [5]
Morphologic Features
On H&E, the tumor is dense, monotonous dermal proliferation of atypical medium-sized lymphocytes. Lymphocytes have irregular and frequently folded nuclei with fine chromatin and moderate nuclear pleomorphism. [6]A perivascular pattern maybe seen (less common).
Usually epidermis is pared, but focal minimal epidermotropism and focal folliculotropism may be seen. Grenz zone separates epidermis from the dermal infiltrate in one third of cases. The proliferation may extend into the subcutis.
Absent or low mitotic activity. Absent or few Plasma cells, histiocytes, neutrophils, and eosinophils.[1][7]
Immunophenotype
Put your text here and fill in the table (Instruction: Can include references in the table)
| Finding | Marker |
|---|---|
| Positive | CD3, CD8, βF1+, TIA1, CD99 |
| Positive (Golgi dot-like) | CD68 |
| Ki-67/MIB1 | <10% |
| Negative ( or Weak) | CD2, CD5, CD7 |
| Negative | CD4, CD56, CD30, Perforin, Granzyme B, PD1, TdT, EBV (always negative) |
One reported case with CD8+, CD4+ phenotype. [8]
Few reported cases had high proliferation index.[9]
The Golgi dot-like staining pattern of CD68 in tumor cells is unique to this entity.[10]
Chromosomal Rearrangements (Gene Fusions)
Chromosomal rearrangements contributing to tumor formation have not yet been described.
Individual Region Genomic Gain / Loss / LOH
Individual region genomic gain, loss or LOH contributing to tumor formation have not yet been described
Characteristic Chromosomal Patterns
Characteristic chromosomal patterns contributing to tumor formation have not yet been described
Gene Mutations (SNV / INDEL)
Gene mutations contributing to tumor formation have not yet been described
Epigenomic Alterations
Epigenomic alterations contributing to tumor formation have not yet been described
Genes and Main Pathways Involved
Gene mutations contributing to tumor formation have not yet been described
Genetic Diagnostic Testing Methods
In nearly all cases, the neoplastic T cells exhibit clonal rearrangements of TR (TCR) genes.[11]
Familial Forms
None.
Additional Information
The tumor generally has an excellent prognosis, with no reported fatal outcomes. Complete remission following surgical excision or local radiation therapy is common. Recurrence after treatment is possible, more frequently in younger patients, and can occasionally occur at other cutaneous sites. Dissemination to extracutaneous sites has been reported in only one case.[11][12]
