RESUMEN
ABSTRACT: When angiosarcoma, a rare and aggressive tumor of the soft tissue, develops in the setting of chronic lymphedema, it is referred to as Stewart-Treves syndrome. It is usually seen in chronic lymphedema of the upper limbs postmastectomy. Angiosarcoma developing in the lower limb in the setting of chronic lymphedema is rare and has a poor outcome. The presentation of angiosarcoma can vary, ranging from a bleeding papule to a plaque or a subcutaneous mass, which can later progress to ulceration or necrosis. Treatment for Stewart-Treves syndrome is aggressive because of its poor prognosis and usually requires a multidisciplinary approach of surgery, radiation, and chemotherapy. Several theories have been put forth to explain the mechanism of Stewart-Treves syndrome, but it remains ambiguous. The current literature regarding angiosarcoma developing in the setting of chronic lymphedema in the lower limb is limited to single case reports. Herein, the authors report a series of six cases of biopsy-proven angiosarcoma in the setting of lower extremity lymphedema. Providers should include angiosarcoma in the differential diagnosis of ulcerative or vascular tumors arising in the context of lower extremity lymphedema.

OBJECTIVES: Angiosarcomas are rare malignant mesenchymal neoplasms of endothelial cell origin with a predilection to the ventral abdominal wall in cats. Larger case series describing this entity are lacking. METHODS: Two referral centre laboratory databases were searched for angiosarcoma of the ventral abdominal wall. Nine cases with a histological diagnosis were included. Immunohistochemistry (factor VIII and PROX-1 antibodies) was used to phenotype them as haemangiosarcoma or lymphangiosarcoma. RESULTS: All cats presented with a ventral abdominal mass, five of which were producing a serosanguinous discharge. Eight underwent tumour staging and pulmonary metastases were suspected in one cat (but not histologically confirmed). With histopathology alone, a diagnosis of angiosarcoma and lymphangiosarcoma was made in four and five cases, respectively. After immunohistochemistry, five cases had a haemangiosarcoma phenotype and four had a lymphangiosarcoma phenotype, including two cases of lymphangiosarcoma that were reclassified as hemangiosarcoma. Eight cats received treatment (either surgery with or without adjuvant therapies or medical management alone). Six cats were euthanased due to local disease progression. The median survival time for haemangiosarcoma was 166 days (range 137-381), and for lymphangiosarcoma it was 197 days (range 67-208). Two cats with haemangiosarcoma remained alive for a follow-up period of 329 and 580 days, respectively. CONCLUSIONS AND RELEVANCE: Feline ventral abdominal angiosarcomas are rare locally aggressive neoplasms. While histology often provides a diagnosis of angiosarcoma, immunohistochemistry is ultimately required to differentiate between haemangiosarcoma and lymphangiosarcoma phenotypes. Further studies are required to evaluate whether the different phenotypes have an impact on treatment response and outcome.

BACKGROUND: Composite haemangioendothelioma is a rare vascular neoplasm with indolent to intermediate malignant potential. Diagnosis of this disease relays on histopathological identification of at least two different morphologically distinctive vascular components in proper clinical settings. Exceedingly rare cases of this neoplasm can exhibit areas resembling high-grade angiosarcoma, which does not change the biological behaviour. Such lesions tend to occur in the setting of chronic lymphoedema and thus, can mimic Stewart-Treves syndrome, which has a much worse clinical outcome and prognosis. CASE PRESENTATION: We present a case of 49 years old male suffering from chronic lymphoedema of the left lower extremity who had developed a composite haemangioendothelioma with high grade angiosarcoma-like areas mimicking the Stewart-Treves syndrome. Given the multifocality of the disease, the only potentially curable surgical treatment would be hemipelvectomy, which was refused by the patient. The patient has been followed-up, with no signs of local progression of the remaining disease, nor a distant spread outside the involved extremity for two years. CONCLUSIONS: Composite haemangioendothelioma represents a rare malignant vascular tumour, with significantly more favourable biological behaviour than angiosarcoma, even in cases where angiosarcoma-like areas are present. For that reason, composite haemangioendothelioma can be easily misdiagnosed as true angiosarcoma. The rarity of this disease unfortunately hampers the development of clinical practice guidelines and the implementation of treatment recommendations. Most of the patients with localized tumour are treated by wide surgical resection, without neo- or adjuvant radiotherapy or chemotherapy. However, in the case of this diagnosis, the watch-and-wait approach is better than mutilating procedure, highlighting the necessity of establishing of the correct diagnosis.

BACKGROUND: stewart-treves syndrome (STS) is an angiosarcoma associated with chronic lymphedema. OBJECTIVES: This article analyses the characteristics of twenty-two patients and proposes active intervention in lymphedema and the early diagnosis of STS. METHODS: Twenty-two patients with STS were diagnosed at the centre over an 11-year period. Clinical manifestations, a series of conventional analyses, and histopathology were used to study these cases retrospectively. RESULTS: The age range of 22 patients with STS was 15 to 78 years. The main clinical manifestations included multiple skin and subcutaneous nodules and scattered red or purplish-red rashes in the lymphoedematous limbs. These patients often showed clinical symptoms such as lymphedema, weakness, emaciation, pain, mass, lymphadenopathy and so on. The positive rates of ultrasonography, MRI and radionuclide imaging were 66.7% (6/9), 92.3% (12/13) and 18.2% (2/11), respectively. The main points regarding active intervention in lymphedema and early diagnosis of STS were summarized. STUDY LIMITATIONS: Since this was a retrospective study, the main points summarized by the author need to be further quantified in clinical work to guide the diagnosis of this kind of disease more conveniently. In addition, further clinical trials are needed to evaluate the role of lymphedema in the occurrence and development of malignant tumors. CONCLUSIONS: STS can appear in lymphoedematous tissue many years after lymphedema onset. To avoid delays in the diagnosis and therapy of STS, physicians should actively look for signs or symptoms of malignant lymphedema during the follow-up period and promptly manage patients developing problems.

Stewart-Treves syndrome (STS) is a rare, cutaneous angiosarcoma associated with chronic lymphedema. The prognosis of this syndrome is extremely poor, with a median survival time of 5-8 months, if untreated. An 82-year-old Asian woman noticed a painless elastic mass with partial discoloration (purplish discoloration) on the left thigh. She had lower lymphedema for 15 years. Lesion biopsy and immunohistochemistry analysis led to the diagnosis of angiosarcoma, which was considered to be STS. She was referred to our department for concurrent chemoradiotherapy. Radiation therapy consisted of 25 daily fractions of 2 Gy each (prescription dose: 50 Gy). Concurrent chemotherapy consisted of 2 monthly cycles of docetaxel (75 mg/body on day 1) and recombinant interleukin-2 (700,000 units/body on days 1-5). She experienced acute adverse events such as Grade 2 dermatitis, Grade 2 anemia, and Grade 4 leukopenia. Posttreatment computed tomography images revealed that lesions had disappeared. Moreover, the accumulation patterns on positron emission tomography images were markedly weakened after the treatment. She exhibited no signs of recurrence for 4 years.

We report 21 cases of a distinctive and unique vascular tumor which we propose to be a pure lymphatic-type angiosarcoma characterized by architectural and growth characteristics of angiosarcoma, cytologic, and immunohistochemical features of lymphatic differentiation, a prominent lymphocytic infiltrate, and variable nuclear grade. Patients included 12 males and 9 females with a median age of 65 years (range: 32 to 95 y). Tumors involved the head and neck (n=11), lower extremities (n=5), trunk (n=4), and upper extremity (n=1) and were located superficially in the dermis and/or subcutis. Tumors were designated "low grade" (n=10) when the nuclear grade was low, and vascular channel formation was evident throughout but with multilayering of endothelium within the vessels. Cases were designated "high grade" (n=11) when nuclei appeared higher grade with more rounded contours and prominent nucleoli and when solid areas predominated over vascular channel formation. A striking feature of both groups was the presence of a dense, lymphocytic infiltrate with occasional germinal center formation. All cases strongly and diffusely expressed at least 1 lymphatic marker (21/21) with podoplanin (17/19) and Prox-1 (11/11) more commonly expressed than LYVE-1 (5/10). No consistent molecular alteration was identified. Follow-up on 17 patients (median: 41 mo, mean: 54 mo) showed 10 patients were alive without disease, 5 were alive with disease, 1 died of other cause, and 1 died of disease. Local recurrence developed in 9 cases and metastasis in 2 cases, although neither correlated with grade as defined. On the basis of clinical follow-up to date, the natural history of lymphatic-type angiosarcoma appears to be more favorable than other forms of cutaneous angiosarcoma.

BACKGROUND: Stewart Treves-Syndrome (STS) was first characterized as angiosarcoma in the homolateral limb of a patient with breast cancer and lymphedema. Now, other conditions represent STS. It's a rare condition. The diagnosis is easier in the presence of single or multiple purple nodules. Even though other dermatological aspects have been reported, no study has grouped its characteristics. AIM: Evaluate the dermatological characteristics of classical STS (c-STS). METHODS AND RESULTS: We report a patient with chronic lymphedema with a history of recurrent erysipelas that rapidly developed multiple papules in the superior limb. It was initially diagnosed as bullous erysipelas, but unsatisfactory evolution led to biopsy, which demonstrated an unsuspected epithelioid angiosarcoma. We have also performed a review of dermatologic aspects of c-STS using PubMed and Lilacs databases. PICTOS methodology and PRISMA flow chart were considered. The main dermatological aspects associated with c-CTS were summarized. Using a systematic evaluation from 109 articles, 29 were selected and 44 patients were described to whom we added one case. The mean time with lymphedema was 10 years. Of the patients analyzed, 97.2% were female; 95.6% were submitted to radical mastectomy; 81.2% presented with multiple lesions, 67.4% of the lesions were reported as nodules or tumors, 53.4% were purple, 33.4% were associated with an ecchymotic halo, and 33.4% were ulcerated lesions. CONCLUSION: When evaluating patients with chronic lymphedema with new dermatological abnormalities, clinical suspicion, or unfavorable evolution, the knowledge of clinical signs is important for diagnosis, and a biopsy must be considered. Papules associated with erythematous-wine color and bluish hematoma aspect must raise clinical suspicion.

Kaposi sarcoma is a vascular sarcoma with 4 clinical variants: classic Kaposi sarcoma, which mainly affect the extremities of elderly patients and follows a chronic, generally indolent course; African Kaposi sarcoma; immunosuppression-associated Kaposi sarcoma; and AIDS-associated Kaposi sarcoma. Type8 human herpesvirus is the etiologic agent in all 4variants. Cutaneous angiosarcoma is a cutaneous neoplasm with a very poor prognosis. It carries a high probability of local relapse and has a 10% to 15% survival rate at 5years. There are 3 main variants of cutaneous angiosarcoma: idiopathic angiosarcoma of the face and scalp; Stewart-Treves syndrome; and postradiation angiosarcoma. The only potentially curative treatment is surgery with or without radiotherapy. However, its indistinct borders and multicentric nature mean that treatment is often palliative with chemotherapy, radiotherapy, or both.

Angiosarcoma (AS) is an uncommon vascular malignancy with an aggressive clinical course. Radiation-associated angiosarcoma (RAAS) and Stewart-Treves syndrome are associated with MYC gene amplification and protein overexpression, while other radiation-associated vascular lesions including atypical vascular lesions (AVL) are not associated with MYC overexpression. In contrast, de novo AS represent a group of molecularly heterogeneous tumours, for which MYC expression has not been extensively examined. In this study, MYC immunohistochemistry (IHC) was performed on representative whole tissue sections of a large retrospective cohort of de novo AS, RAAS, Stewart-Treves syndrome, and AVL and evaluated using a semi-quantitative scoring method. MYC is strongly expressed in the majority of RAAS and Stewart-Treves syndrome. De novo AS demonstrate variable MYC expression, with high-grade tumours showing significantly higher MYC expression than low-grade tumours. In contrast, MYC expression in AVL is predominantly negative but may occasionally show focal staining. These results indicate that unequivocal strong MYC IHC staining supports the diagnosis of RAAS. In rare cases of RAAS without strong MYC expression, however, particularly relatively low-grade tumours for which the differential diagnosis includes AVL, the distinction between these lesions should be made on morphological grounds using previously established criteria (i.e., significant atypia, deep invasion, infiltrative growth, etc.). Increased MYC expression in high-grade de novo AS suggests that MYC overexpression may play a role in the pathogenesis of these tumours, and MYC IHC may be a prognostic and/or therapeutic biomarker in a subset of these tumours.

BACKGROUND: Pancreatic involvement of angiosarcoma is extremely rare. METHODS: We herein report a rare case of angiosarcoma associated with chronic lymphedema (Stewart-Treves syndrome) with pancreatic metastasis that was diagnosed using endoscopic ultrasound (EUS)/fine needle aspiration (FNA). RESULTS: A 43-year-old woman with a history of radical hysterectomy with bilateral inguinal lymphadenectomy and chemoradiotherapy for cervical cancer 15 years prior noticed the presence of erythematous indurative plaques on her right femoral region, where chronic lymphedema had developed. Contrast-enhanced computed tomography (CT) revealed not only multiple nodules in the subcutaneous tissue of the right femoral region but also a 25âmmâ×â20âmm solid mass in the region of the pancreatic tail. A histological analysis of the specimens obtained using EUS/FNA revealed angiosarcoma that was immunohistochemically positive for platelet/endothelial cell adhesion molecule-1 but negative for cytokeratin. The patient was diagnosed as Stewart-Treves syndrome that had metastasized to the pancreas. Chemotherapy was performed, but the patient died 14 months after her diagnosis. CONCLUSION: Unfortunately, this patient was not followed up, even though she had chronic lymphedema of the right femoral region due to the repeated occurrence of phlegmon. To improve the survival rate of this fatal secondary malignant complication of radical lymphadenectomy, an early diagnosis with consecutive and long-term clinical follow-up and close monitoring for Stewart-Treves syndrome is therefore important.

Lymphangiosarcoma (LAS) is an uncommon malignant neoplasia arising from lymphatic endothelium; little information exists regarding therapy. Single institutional retrospective review for canine LAS histopathology diagnoses over a 15-year period yielded 12 dogs. Ten dogs were presented for a mass and/or swelling at cervical, trunk or limb regions. Prior to diagnosis, 10 dogs received empiric wound therapy. Cytology performed in 10 consisted of mild inflammation. Survival ranged from 60, 168 and 876 days for three dogs with palliation; 90 days with prednisone in one; 182 days with chemotherapy in one; 240, 267, 487, 630 and 941 days for five receiving surgery; and 574 days for one receiving surgery, radiation and chemotherapy. One dog is alive with recurrence at 243 days following surgery and carboplatin chemotherapy. Clinical improvement existed in LAS dogs receiving multimodal therapies. Early tissue biopsies are recommended for progressive oedematous lesions of unknown origin.
