Lymphangioma-Like Kaposi Sarcoma.

August 2012

We report on a recent lesion in a 75-year-old woman who

had been diagnosed with classic Kaposi sarcoma (KS) 8 years earlier, at which time she presented with plaques on the right thigh and right forearm (Fig. 1A) and no metastasis was detected. Findings from the initial biopsy of the forearm lesions were compatible with nodular KS.

During the 8-year follow-up, the patient developed 7 recurrent skin tumors on the forearm and legs. Each tumor had the same clinical appearance in the form of plaques (Fig. 1B), and no systemic involvement was detected at any time. The lesions were treated with liposomal doxorubicin. Biopsies were taken from the forearm at each recurrence and histology continued to show findings consistent with nodular KS mixed with lymphangioma-like areas. 

These areas were comprised of irregularly-dilated ectatic vascular spaces in the reticular dermis that were lined by moderately atypical endothelial cells. These spaces were greater in number and size than normal lymphatic vessels (Fig. 2). Immunohistochemistry showed strong CD34 positivity. Endothelial cells lining the lymphangioma-like areas of the tumor were

also positive on staining with human herpes virus type 8

(HHV-8) antibody (Fig. 2C) and the lymphatic endothelial

marker podoplanin (D2-40) (Fig. 2D). Based on these findings, the patient was diagnosed with lymphangioma-like KS.

Seven months after completing the most recent cycle of

chemotherapy with doxorubicin, the patient presented with a serious recurrence consisting of localized, multinodular, ulcerated lesions on both legs but more severe on the right thigh; severe lymphedema was also noted (Fig. 1C). She was given radiotherapy, second-line chemotherapy with paclitaxel (taxol), and thorough local treatments. At the time of writing the lesions remained ulcerated and had not changed in size. The patient attended scheduled follow-up visits and did not show signs of systemic spread of disease.

CASE REPORT

A 30-year-old homosexual male was recently diagnosed with HIV infection (category A2). He was been admitted into the hospital because of anal pain and diarrhea of 8 months. He presented purplish cutaneous lesions, laterocervical adenopathies and a palpable anal mass. The rest of physical exploration did not reveal any other significant alteration. The amount of CD4 was 350 cells/mL and the viral load of 10,000 copies/mL. Fecal cultures were negative. A colonoscopy was performed and detected an ulcerated rectal mass that was biopsied (Fig. 1). He presented an episode of hematemesis so it was performed an upper endoscopy which demonstrated the presence of lesions suggestive of Kaposi’s in the stomach (Fig. 2) and duodenum (Fig. 3). The definitive anatomopathologic diagnosis of the cutaneous anal lesion, gastric biopsy and adenopathies was Kaposi’s sarcoma. The patient began antiretroviral treatment and

chemotherapy with liposomal doxorubicin and radiotherapy.

DISCUSSION

Kaposi’s sarcoma is a vascular tumor described first in 1872. It is associated with the immunosuppressive state in patients affected by infection with HIV. It usually appears as small purplish cutaneous lesions although it can affect other mucosa, organs and lymphatic system. Postmortem studies suggest the presence of visceral involvement in more than 75% of the

cases, being the lungs and gastrointestinal tract the most common ones. It can affect any part of the digestive tract, from the oropharynx to the rectum. They have been described cases of hepatic, splenic and pancreatic disease (1). Gastrointestinal Kaposi’s sarcoma frequently has a silent clinical course although it can cause abdominal pain, gastrointestinal bleeding and

intestinal obstruction (2). Endoscopically it can presents as a purplish nodule, a polipoid mass or a hemorragic macule (3).

Kaposi Sarcoma (KS) is a rare entity. In the north west of Pakistan and Aghanistan, we mostly come across non-HIV related Kaposi sarcoma as Human Immunedeficiency Virus (HIV). Infections are rare in this part of the world. Here, we present a case of a non-auto Immunedeficiency Disease (AIDS) related KS. A 45-year-old male, Afghan patient presented to our oncology outpatient's unit with multiple subcutaneous nodules. The sites of involvement were the periorbital region, retro-auricular region, forearms, legs, chest and back. Oral mucosa was spared at the nodules. The patient had no visceromegaly at the time of presentation. A biopsy specimen from the retro-auricular region revealed a KS with dermal lymphatic involvement. His serum was negative for the common types of viral infections including Human Immunodeficiency Virus (HIV) on routine serology. His total B-lymphocytes (CD 19+), total T-lymphocyte (CD3+), total CD4+ lymphocyte (CD3+, CD4+) and total CD8+ (CD3+, CD8+) counts were all normal or borderline high. The patient was under treatment with 3 weekly chemotherapeutic regimens of Adriamycin, Bleomycin, Vincristine (ABV) keeping in view socioeconomical constrains, logistical difficulties in getting proper medical care and side effects of other options like radiotherapy for extended surface areas.
