Squamous cell carcinoma, lymphoma and bacillary angiomatosis
are among the differential diagnoses of KS.
The bacterium was also found to cause endocarditis, peliosis hepatis, and bacillary angiomatosis
It has been reported to lead to bacillary angiomatosis
in patients who are HIV positive.
henselae infection can be particularly severe for patients with immunocompromising conditions, such as AIDS, in whom vascular proliferative lesions (bacillary angiomatosis
and bacillary peliosis) may develop (5).
(6) Bacillary angiomatosis
caused by Bartonella henselae or Bartonella Quintana is one of the pathognomonic conditions of HIV.
henselae is the aetiological agent of cat-scratch disease, bacillary angiomatosis
, meningo-encephalitis and chronic bacteraemia.
Cats associated with cat-scratch disease are highly likely to be bacteremic with Bartonella henselae; however, even 28% of cats without known associations to cat-scratch disease or bacillary angiomatosis
have Bartonella henselae bacteremia .
Other differential diagnoses of AHE includes vascular tumors and tumor-like conditions of blood vessels, such as angiosarcoma, cutaneous epithelioid angiomatous nodule, bacillary angiomatosis
, and epithelioid hemangioendothelioma.14
Infection may result in bacteremia (presence of bacteria in the blood), myocarditis (inflammation of the middle layer of the heart wall), peliosis hepatis (a vascular condition which results in blood-filled sacs in the liver), neuroretinitis (inflammation of the neural retina and optic nerve), bacillary angiomatosis
(a proliferation of blood vessels leading to tumorlike masses), enlarged lymph nodes, and fevers.
Skin lesions of secondary syphilis in patients with HIV may have varied appearance that mimic other diseases like cutaneous lymphomas, mycobacterial infections, bacillary angiomatosis
, fungal infections or Kaposi's sarcoma (6).
(5,6) The differential diagnosis should include hemangioma, bacillary angiomatosis
, peripheral giant cell granuloma, peripheral ossifying fibroma, and some malignancies, such as Kaposi sarcoma, squamous cell carcinoma, and achromic melanoma.
