Epithelioid angiosarcoma of the orbit presenting as Tolosa-Hunt syndrome. A clinicopathologic case report with review of the literature

Angiosarcoma of the eyelid and periorbital region. Experience in Leiden with iridium192 brachytherapy and low-dose doxorubicin chemotherapy

AIM

To report on the use of iridium(192) brachytherapy and doxorubicin chemotherapy as adjuvant therapy in 6 patients with angiosarcoma of the eyelid and periorbital region.

MATERIAL AND METHODS

Tumor localization and diameter, signs of inflammation, histology and treatment are discussed in this retrospective study of 6 patients (age 46-87 yrs.) presenting with primary angiosarcoma in the eyelid.

RESULTS

Six patients (4 elderly) with angiosarcoma localized in one or more eyelids, the face or multilocular were seen between 1987 and 2000. In one patient, a small nodular tumor did not recur within 4 years after radical excision. In another patient, the tumor was treated with surgery and iridium(192) wire brachytherapy and did not recur in 17 years of follow-up. In four patients with large diffuse tumors that were treated with doxorubicin, partial regression was achieved. The follow-up was >3 years (median 5 years).

CONCLUSION

If radical surgery for angiosarcoma of the eyelid and periorbital region is not possible, adjuvant iridium(192) wire brachytherapy may prove beneficial. For widespread, diffusely growing tumors, and in elderly patients, low-dose (slowly, 20 mg i.v.) doxorubicin can be used weekly as adjuvant therapy, resulting in partial regression and longer survival rates than previously published by other authors.

An approach to the patient with painful ophthalmoplegia, with a focus on Tolosa-Hunt syndrome

The differential diagnosis of painful ophthalmoplegia is extensive and consists of numerous sinister etiologies, including neoplasms (ie, primary intracranial tumors, local or distant metastases), vascular (eg, aneurysm, carotid dissection, and carotid-cavernous fistula), inflammatory (ie, orbital pseudotumor, giant cell arteritis, sarcoidosis, and Tolosa-Hunt syndrome), and infectious etiologies (ie, fungal and mycobacterial), as well as other miscellaneous conditions (ie, ophthalmoplegic migraine and microvascular infarcts secondary to diabetes). A systematic approach to the evaluation of painful ophthalmoplegia can lead to prompt recognition of serious disorders that can be associated with significant morbidity or mortality if left untreated. Inflammatory conditions such as Tolosa-Hunt syndrome and orbital pseudotumor are highly responsive to corticosteroids but should be diagnoses of exclusion.

Primary Epithelioid Angiosarcoma of the Male Breast: Report of a Case

We report a case of primary epithelioid angiosarcoma of the male breast. The patient was a 20-year-old Chinese man who presented with a huge tumor just below the left nipple. Histopathological examination and immunohistochemical analysis confirmed a diagnosis of primary epithelioid angiosarcoma of the male breast, without axillary lymph node metastasis. We review the relevant literature on this rare malignant tumor.

Painful ophthalmoplegia: Overview with a focus on tolosa-hunt syndrome

Painful ophthalmoplegia is an important presenting complaint to emergency departments, ophthalmologists, and neurologists. The etiological differential diagnosis of painful ophthalmoplegia is extensive and consists of numerous sinister etiologies including vascular (eg, aneurysm, carotid dissection, carotid-cavernous fistula), neoplasms (eg, primary intracranial tumors, local or distant metastases), inflammatory conditions (eg, orbital pseudotumor, sarcoidosis, Tolosa-Hunt syndrome), infectious etiologies (eg, fungal, mycobacterial), and other conditions (eg, microvascular infarcts secondary to diabetes, ophthalmoplegic migraine, giant cell arteritis). A systematic approach to the evaluation of painful ophthalmoplegia can lead to prompt recognition of serious disorders that if left untreated, can be associated with significant morbidity or mortality. Inflammatory conditions such as Tolosa-Hunt syndrome and orbital pseudotumor are highly responsive to corticosteroids, but should be diagnoses of exclusion.

Epithelioid hemangioma of the penis: a clinicopathologic and immunohistochemical analysis of 19 cases, with special reference to exuberant examples often confused with epithelioid hemangioendothelioma and epithelioid angiosarcoma

Epithelioid hemangiomas of the penis are very rare. To date, less than 10 examples have been reported in the English language literature. In this report, we describe the clinical, histopathologic, and immunohistochemical findings in 19 cases retrieved from our files. The patients ranged in age from 23 to 75 years (median age, 45 years) at the time of initial surgical resection. Seventeen patients presented with a solitary mass, and two presented with two separate, but closely approximated, lesions. The process involved the glans penis (n = 3), shaft (n = 11), base of the penis (n = 2), or penis, not otherwise specified (n = 3). The lesions ranged in size from <0.5 to 2.5 cm (median size, approximately 1.2 cm) in greatest dimension. Eleven examples were specifically noted to be dorsally located, and only one was stated to be ventral. Localized pain or tenderness was the most common complaint, documented in 12 cases. The preoperative duration of the lesions ranged from 5 days to 1 year (median 4.5 months). Microscopically, all examples contained a tumefactive proliferation of epithelioid endothelial cells, often in a nodular or lobular configuration and associated with an inflammatory infiltrate containing lymphocytes and eosinophils. In 14 cases, the vascular proliferation was associated with a small arterial segment, sometimes with mural damage and frequently (n = 13) with intraluminal epithelioid endothelial cells. Based on the growth pattern of the epithelioid endothelial cells, 13 cases were considered "typical," and six were considered exuberant or "atypical." The latter examples had a prominent centrally located zone where nests or sheet-like aggregates of epithelioid endothelial cells did not form discrete vessels. Immunohistochemical data are available for 15 tumors. The epithelioid endothelial cells usually had strong reactivity for CD31, lesser reactivity for factor VIIIrAg, and minimal reactivity for CD34. In 9 of 12 cases, a small number of epithelioid endothelial cells expressed keratins. In all cases tested, at least focal muscle-specific actin-positive myopericytic cells were present bordering the endothelial cells, and this was especially notable peripherally. Initial surgical intervention consisted of either a shave biopsy (n = 1), excisional biopsy (n = 2), or local excision (n = 16). A complete follow-up history is available for 12 patients, and incomplete follow-up information is available for an additional four patients. One patient developed a new epithelioid hemangioma at a site within the penis separate from the initial lesion, but no patient is known to have experienced a true metastasis or to have died of complications of this process. Optimal management appears to be complete local excision with periodic follow-up visits to monitor for local recurrence.

Cardiac epithelioid angiosarcoma presenting as cutaneous metastases

BACKGROUND

Cardiac angiosarcoma is a rare tumor that has a predilection for middle-aged males and a marked predominance in the right atrium. The tumor may present abruptly with a fulminant clinical course. Initial presentation with metastatic disease is rare. Only one case has been reported of a patient who presented with cutaneous metastases.

METHODS AND RESULTS

We here report the case of a 51-year-old man who initially presented with cutaneous metastases in the absence of cardiac symptoms. The skin biopsy was diagnosed as metastatic undifferentiated sarcoma. The patient died 26 days later with widely disseminated disease. At autopsy a tumor arising in the wall of the left atrium and in the interatrial septum was found. After an immunohistochemical study including CD31 and CD34 stains the diagnosis of cardiac pure epithelioid angiosarcoma was made. To the best of our knowledge this tumor variant has not been documented in the heart until now.

CONCLUSION

Although cardiac angiosarcoma is a rare neoplasm, its presence should be suspected in patients with cutaneous metastatic angiosarcoma without an evident source of the tumor, even in absence of cardiac symptoms.

Hemangioendothelioma of orbit

Hemangioendothelioma of the orbit is a rare condition which usually occurs in young adult with mean age group of 24 years. Very few cases had been reported in the literature. We describe here a case of hemangioendothelioma in a female of 30 years who came with history of pen-etrating foreign body entering into right eye and fluctuating painful swelling in the lower lid with decrease in the vision. The patient's presentation simulated malignancy of maxillary an-trum, however, the diagnosis was confirmed by histopathology.

Vascular tumors of the orbit

Eighty-five vascular lesions of the orbit examined and treated between 1963-1993 were reviewed retrospectively to reveal the types of vascular tumors, age and sex distribution, clinical characteristics, treatment options and prognosis. Capillary hemangioma was the most frequent orbital vascular tumor accounting for 37 of 85 cases making up 43.5% of the entire orbital masses. Cavernous hemangioma accounted for 35 cases (41.2%), varices for 3 cases (3.5%), anteriovenous malformations for 3 cases (3.5%), angiosarcomas for 3 cases (3.5%), lymphangiomas for 3 cases (3.5%) and hemangiopericytoma for one case (1.2%). Of the 85 vascular tumor cases 43 were encountered in children aged 18 years or less. Capillary hemangioma was the most frequent pediatric orbital vascular lesion, making up 86% of the vascular tumors in this age group. Capillary hemangiomas have been treated with observation and intralesional corticosteroid injections. Cavernous hemangiomas, vascular malformations, lymphangiomas and two cases of angiosarcomas received orbitotomy. One case each of angiosarcoma and hemangiopericytoma underwent exenteration because of the advanced stage of the lesion. There was one tumor-related death who was a 9-year-old boy diagnosed with angiosarcoma. Vascular tumors with the exception of angiosarcomas and hemangiopericytoma behaved as benign lesions.

Cutaneous epithelioid angiosarcoma: a clinicopathological study of four cases

Four cases of cutaneous epithelioid angiosarcoma are described together with the potential diagnostic trap of mistaking these tumours for poorly differentiated carcinoma or malignant melanoma. The immunophenotypic profile using four endothelial markers showed positive staining in all cases for factor VIII related antigen in a predominantly paranuclear dot-like fashion and for CD31 (JC70); in three cases for CD34 (QB-END/10) and in two cases with UEA-1. All four cases were cytokeratin (CAM 5.2 and AE1/AE3) negative in contrast to the positive staining reported at non-cutaneous sites. Aberrant S-100 protein expression was seen in one case. In two cases subsequent recurrences showed better differentiation than the original tumour. Electronmicroscopy confirmed the absence of non-endothelial lines of differentiation but failed to reveal Weibel-Palade bodies.

Epithelioid hemangioendothelioma of the orbital bones

PURPOSE

The authors report a case of an epithelioid hemangioendothelioma arising in the orbital bones. A review of the literature related to this rare orbital neoplasm identified eight well-documented cases, one of which occurred in a patient younger than that reported here, but none of which originated in bone.

METHODS

A 3 1/2-month-old boy had a left inferior orbital mass that had grown rapidly over a 3-day period. An emergency computed tomography scan showed a large neoplasm with significant bone destruction of the zygoma and maxilla. Initial examination suggested a rhabdomyosarcoma, and a transconjunctival biopsy was performed, which was complicated by significant blood loss. The final pathologic diagnosis was an epithelioid hemangioendothelioma, or grade 2 hemangioendothelioma, of bone origin. No other sites of disease were found on metastatic survey. Subsequent treatment consisted of an en bloc tumor resection sparing the orbital soft tissues and globe.

RESULTS

The patient is free of disease and has normal visual fixation and ocular motility 20 months after surgery.

CONCLUSION

Epithelioid hemangioendothelioma, a vascular malignancy of endothelial cell origin, very rarely involves the orbit. This case is notable for its early development, rapid growth, bony origin, and epithelioid histology.

Steroid-responsive painful ophthalmoplegia in childhood: sphenoid sinusitis presenting as Tolosa-Hunt syndrome

A childhood case of painful ophthalmoplegia which responded well to steroids was described. Although the clinical features suggested Tolosa-Hunt syndrome (THS), serial magnetic resonance imagings (MRI) revealed ethmoid and sphenoid sinusitis in this 7-year-old boy. It was considered that multiple factors such as allergy, viral infection and swimming predisposed him to develop severe sinusitis and gave rise to his painful ophthalmoplegia.

Infantile subconjunctival and anterior orbital fibrous histiocytoma. Ultrastructural and immunohistochemical studies

A fleshy, polypoidal and partially lobulated lesion that protruded between the eyelids from the medial caruncular region and that infiltrated the contiguous anterior orbital tissues developed over 1 month in a 9-month-old infant. The microscopic features of the tumor included a plump spindle cell population, more polygonal cells, early xanthoma cell transformation, infiltrating lymphocytes and eosinophils, and multinucleated giant cells, the last not exhibiting classic Touton characteristics. The histopathologic differential diagnosis ranged among fibrous histiocytoma, juvenile xanthogranuloma, and eosinophilic granuloma (histiocytosis-X). Results of electron microscopy disclosed abundant rough-surfaced endoplasmic reticulum, a paucity of lysosomes, and no Langerhans' (Birbeck) granules. Immunohistochemistry corroborated the fibrohistiocytic nature of the tumor, because histochemical stains for the enzymes alpha-1-antichymotrypsin and lysozyme, and monoclonal or polyclonal antibodies against common leukocytic antigen and S-100 protein, were negative--whereas they would have been expected to be positive in various combinations in the different histiocytic proliferations. Vimentin was identified in the tumor cells; this is an intermediate cytoplasmic filament almost always present in mesenchymal proliferations. The distinctions between fibrous histiocytomas of stromal cell origin and true histiocytic proliferations of bone marrow cell provenance are explored.

Painful ophthalmoplegia (Tolosa-Hunt variant): autopsy findings in a patient with necrotizing intracavernous carotid vasculitis and inflammatory disease of the orbit

A 79-year-old man with unremitting painful ophthalmoplegia had a necrotizing inflammatory process that involved the intracranial and intracavernous portions of the right internal carotid artery. The condition ultimately resulted in rupture of the carotid vessel and death. At autopsy, thrombophlebitis of the sphenopalatine sinus was also noted. To our knowledge, this is the second reported autopsy study of painful ophthalmoplegia and chronic nongranulomatous inflammation that involved the carotid siphon and the cavernous sinus.

Orbital angiosarcoma with subconjunctival presentation. Report of a case and literature review

An otherwise healthy 37-year-old woman had, over the course of 2 years, a recurring subconjunctival lesion associated with blepharoptosis. Computed tomography (CT) demonstrated a large anterior and superior orbital mass. A diagnosis of angiosarcoma (AS) was made from biopsy material. The patient is alive and well 18 months after exenteration and radiation therapy. The clinical and histopathologic features of this tumor are discussed with emphasis on the differential diagnosis of malignant vascular tumors of the orbit.

Applications of immunohistochemistry to ophthalmic pathology

Immunohistological techniques have been increasingly used, both in general and ophthalmic pathology, for identification of specific cell types that may not be possible on morphological grounds or by conventional histochemical methods alone. Enzyme conjugate techniques using the peroxidase-antiperoxidase (PAP) immune complex method and the avidin-biotin-horseradish peroxidase method (ABC) are particularly useful as they are highly sensitive, provide permanent results, allow the use of paraffin-embedded tissues and do not require a fluorescent microscope. Antibodies against glial fibrillary acidic protein (GFAP), factor VIII-related antigen, muramidase, S-100 protein, myoglobin, prostatic acid phosphatase and prostate-specific antigen are valuable tools in surgical pathology and their applicability to ophthalmic pathology have been clearly demonstrated.
