The presentation and survival of patients with non-cutaneous AIDS-associated Kaposi's sarcoma.
BACKGROUND
Acquired immune deficiency syndrome related Kaposi's sarcoma (AIDS-KS) remains a significant cause of morbidity and mortality. We describe for the first time a proportion of patients with AIDS-KS who presented with no evidence of cutaneous disease.


METHODS
From our cohort of 5932 individuals infected with the human immunodeficiency virus (HIV-1) treated in the HAART era, 319 were identified with KS. Of these, 11 patients (5.4%) were diagnosed with KS without the presence of any cutaneous disease. We compared their survival, clinical, immunological and virological characteristics to other individuals with KS.


RESULTS
There were no statistically significant differences in survival, CD4 count or HIV viral load at KS presentation. We observed that tumour-associated oedema (P = 0.046) and non-oral gastrointestinal KS (P = 0.042) were significantly more common in patients with non-cutaneous KS. Only one case of non-cutaneous KS was observed prior to the era of highly active anti-retroviral therapy (HAART).


CONCLUSIONS
Non-cutaneous KS is a recognisable condition; patients should be treated with the standard of care as their prognosis is not inferior. This is likely to reflect a strong immune response, in the era of HAART.
