Presentation reference

Is it this?

Reference only, to read alongside your own examination.

Symptoms — what the patient reports (3)

  • The best-known form is in people whose immunity is suppressed, by AIDS or by the drugs given after an organ transplant
  • The cause is human herpesvirus 8, also called the Kaposi sarcoma herpesvirus
  • Red flag: the course differs by form, from indolent to aggressive and fatal in the anaplastic types

Signs — what you find (2)

  • Skin exam looks for purplish lesions or enlarged lymph nodes as possible Kaposi sarcoma [lymphadenopathy]
  • Mucocutaneous surfaces get particular attention since they're a common site for lesions to appear

Tests (4)

  • Definitive diagnosis needs a biopsy or excision of the suspicious area
  • Pathology shows the characteristic spindle-cell vascular proliferation within the dermis
  • Positive LANA1 staining, a marker for HHV-8, on immunohistochemistry helps separate Kaposi sarcoma from look-alike lesions
  • Immunostains for this tumor also come back positive for BCL-2, CD34, PECAM-1, factor VIII, D2-40, and VEGFR-3

If not this — what else fits (6)

  • On histology, Kaposi sarcoma's spindle-cell vascular pattern overlaps with granuloma annulare, spindle cell or tufted hemangioma, kaposiform hemangioendothelioma, angiosarcoma, and several other spindle-cell tumors
  • On mucocutaneous surfaces, Kaposi sarcoma must be distinguished from nevi, pyogenic granuloma, bacillary angiomatosis, hemangioma, angiosarcoma, and melanoma
  • The classic form sits on the legs of elderly men of Mediterranean or Eastern European descent
  • The endemic African form is in children, with lymph nodes enlarged all over the body
  • The HIV-related form is in a patient not taking antiretroviral therapy, spread through skin and internal organs
  • The iatrogenic form is in a patient suppressed by treatment, spread the same way

NO DRUG THERAPY IN PRIMARY CARE (REFERRAL & ADVICE)

1st line
Adult dose and duration

A vascular malignancy presenting as purple-red patches, plaques, or nodules on the skin, strongly associated with HIV/AIDS and immunosuppression; the GP's role is recognising the lesion, testing for HIV, and referring to oncology/dermatology for biopsy and specialist treatment. - Refer, with advice

Paediatric dose

Children follow the same pathway: recognise and refer. No primary-care medicine is implied.

Dose source

No dose - referral pathway, no medicine given in primary care

Why

A vascular malignancy presenting as purple-red patches, plaques, or nodules on the skin, strongly associated with HIV/AIDS and immunosuppression; the GP's role is recognising the lesion, testing for HIV, and referring to oncology/dermatology for biopsy and specialist treatment.

Cautions
  • Undiagnosed HIV infection must be considered and tested for in any patient with suspicious lesions.
  • No medicine is prescribed for this in primary care - this entry is for recognition and referral. Anything given is decided by the service it is referred to.
  • RED FLAG - Pulmonary involvement in Kaposi sarcoma causes respiratory distress and is a major cause of death.
  • RED FLAG - Visceral organ involvement, particularly in the lungs, carries a worse prognosis.
  • RED FLAG - Rapidly spreading lesions or involvement of internal organs indicate advanced disease.
