FIVE UNUSUAL CASES OF PROPTOSIS

Primary orbital hemangiopericytoma: an unusual cause of unilateral proptosis.

numerous orbital neoplastic and non neoplastic processes. Various mesenchymal tumours of both fibrohistiocytic and vascular origin are well-described causes. Hemangiopericytomas (HPC) are rare vascular tumours which can infrequently involve the orbit and their incidence is estimated to be 0.8% to 3% of primary orbital tumours1,2. We herein report a new case of orbital HPC revealed by unilateral...

Amyloidosis; five cases of primary generalized amyloidosis and some other unusual cases.

A conception of amyloidosis as merely a complication of chronic syphilitic, tuberculous or septic disease of bones and joints or of chronic intrathoracic sepsis is no longer adequate. This older view has had to be modified as the association of amyloidosis with other diseases came to be recognized: the predisposing diseases are now known to include rheumatic and rheumatoid affections, myelomato...

Unusual presentation of gestational trophoblastic neoplasm: Report of two cases

  Abstract: Gestational Trophoblastic Neoplasm (GTN) is among rare human tumors which can be observed with widespread metastasis. Two young patients with emergent neurologic symptoms with no gynecological problems are presented in this report. GTN was later diagnosed in both cases with brain metastasis. The first case: A 22 years old patient, admitted to the infectious disease ward, with probab...

Unilateral Proptosis of Unexplained Origin: Report of Nine Cases.

REESE (1951) and other authors hold that, except when an orbital tumour is palpable, no surgery should be attempted unless a deep orbital tumour affects the function of the eye or the optic nerve. Reese recalled no case in which the orbit had been explored with benefit, merely because of an unexplained unilateral proptosis. Among my series of 130 cases of unilateral proptosis, mostly caused by ...
