ManifestationThis section has been translated automatically.
Preferably persons > 50 years. Rarely described in childhood. No gender preference.
LocalizationThis section has been translated automatically.
especially the lower extremity.
Clinical featuresThis section has been translated automatically.
Onset with a clinical picture "reminiscent of an infection" with a pronounced general feeling of illness, fever, weight loss.
The skin findings are atypical for cutaneous T-cell lymphoma. There are usually asymptomatic or slightly painful, subcutaneous, red (inflammatory), plate-like or nodular indurations measuring 5.0-20.0 cm in diameter, so that the first clinical impression is more reminiscent of erythema nodosum or atypically localized erythema induratum. Long-term relapsing courses with spontaneous remissions are the rule. Ulcerations are the exception (in about 6% of patients).
If a hemophagocytosis syndrome is detected (in about 17% of patients), the prognostically unfavorable subcutaneous form of systemic gamma/delta T-cell lymphoma must be considered. In this case, sepsis-like clinical pictures may develop.
HistologyThis section has been translated automatically.
Dense, nodular infiltrate in the subcutis, with very pleomorphic lymphoid cells of different sizes, which often accumulate in a ring around lipocytes (so-called rimming). General view as in lobular panniculitis. Angiocentric growth pattern with fat tissue necroses. Granulomatous secondary reaction, erythrophagocytosis in 30% of cases.
Clonal rearragenment of TZR genes can be detected in most cases.
Immunocytogenetic. Expression of the alpha/beta T cell receptor (TZR). Expression of the beta/gamma chain of the T cell receptor indicates subcutaneous infiltration of the systemic form of gamma/delta T cell lymphoma (GD-TZL) with poor prognosis.
Differential diagnosisThis section has been translated automatically.
- Panniculitis: Mostly subacute, mostly painful nodular subcutaneous infiltrates.
- Profound circumscribed scleroderma: Slow, non painful, firm indurations. Histology is diagnostic.
- Subcutaneous form of gamma/delta T-cell lymphoma: expression of the gamma/delta chain of TZR. Important DD(!) because systemic gamma/delta T-cell lymphoma has a significantly worse prognosis.
- Lupus panniculitis: infiltration by small lymphocytes, no cell atypia.
- Extranodal NK/T-cell lymphoma: expression of CD56; association with EBV.
Progression/forecastThis section has been translated automatically.
Mostly slow progressive course. 5-year survival rate of 80%.
Case report(s)This section has been translated automatically.
The 48-year-old patient reported a changeable clinical picture with little pain, plate-like indurations, which receded under leaving behind deeply indented, also extensive "scarring" of skin and subcutis. Since 1 year his analogous changes also occurred in the lower abdomen.
The general condition of the patient was unremarkable.
Laboratory: unremarkable findings for blood and differential blood count. Liver enzymes, lipase, amylase, alpha-1-antitrypsin, kidney values o.B. No pathological immune parameters. Borrelia serology normal.
Imaging procedures: o.B.
Histopathological and molecular biological findings: Dense, nodular infiltrate in the subcutis, with very pleomorphic lymphoid cells of different sizes, which often accumulate in a ring around lipocytes (so-called rimming). General view as in lobular panniculitis. Immunohistology: Tumor cells express T cell markers: CD3, CD8, CD43, CD45RO, CD4 is not expressed! Clonal rearragenment of TZR genes was detectable.
Ther: Initiation of a steroidal monotherapy (prednisolone 1mg/kg/KG i.v.). After 8 weeks complete regression of the indurations. Maintenance dose 5mg/p.o. After 6 months local recurrence. Now radiotherapy (GD 36 Gy, fractionation 5 x/week 2.0Gy). Including complete regression and 2 years without recurrence.
