Haematolymphoid Tumours (5th ed.)

(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.

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

Solitary or multiple (rare) [1] [3] [4]

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]

Negative ( or Weak) CD2, CD5, CD7
Negative CD4, CD56, CD30, Perforin, Granzyme B, PD1, TdT, EBV

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]

None.
