摘要:

Computerized tomography scan evidence of periosteal elevation in patients with orbital cellulitis is interpreted in the current medical literature as an indication of subperiosteal abscess. We present three such cases in which surgical drainage yielded clear fluid or granulation tissue rather than pus. A fourth case resolved on antibiotic therapy alone. Cases of periosteal elevation that resolve without surgery may represent inflammatory effusion, infections of lesser virulence, or propagation of granulation tissue rather than true abscesses. We suggest that periosteal elevation seen in patients with orbital cellulitis should represent a relative rather than an absolute indication for drainage surgery.

摘要:

A 60-year-old man developed a subcutaneous mass in the right lower eyelid 2½ years after enucleation of the left eye for a mixed-cell-type choroidal melanoma. Excision of the subcutaneous eyelid mass revealed the tumor to be a malignant melanoma composed of spindle B cells similar to those in the intraocular tumor. The patient's systemic evaluation, including liver enzymes, has remained normal, with no signs of further metastasis and no evidence of another primary melanoma for 14 months of postexcision follow-up. The significance of the rare occurrence of isolated metastatic melanoma from the choroid of one eye to the eyelid of the other is discussed.

摘要:

A 38-year-old man presented with hyperophthalmia, enophthalmos, and upper eyelid retraction 18 months following an osteoplastic flap and frontal sinus obliteration for mucocele. Computerized tomography confirmed the presence of frontal bone absorption in the roof of the orbit with traction and elevation of the orbital contents into the obliterated frontal sinus. A fracture of the orbital roof with penetration of periorbita at the time of original surgery was the suspected precipitating cause of the complication. Surgical management included lysis of the cicatrix between the orbit and frontal sinus and interposition of a silicone sheet between the orbit and sinus, which restored the appropriate anatomic relationships and prevented recurrence.

摘要:

A modified technique for the repair of moderate to severe cicatricial entropion has been developed. This method is unique, as it involves the creation of a bipedicled tarsoconjunctival advancement flap. The technique avoids the causes of surgical failure seen with standard tarsal fracturing procedures.

摘要:

A 91-year-old man developed a mass in the right medial canthal and lacrimal sac region, which was found histopathologically to be a poorly differentiated neoplasm. The results of a complete systemic evaluation, including urologic consultation, rectal examination, bone scan, and determination of serum acid phosphatase level, were normal. In spite of the negative evaluation for prostatic carcinoma, immunohistochemical studies using immunoperoxidase stains for prostaticspecific antigen demonstrated that the lacrimal sac tumor was metastatic carcinoma from an occult primary neoplasm in the prostate gland. The presence of tumor in the prostate gland was then confirmed by a needle biopsy. Modern immunohistochemical techniques are particularly valuable in the diagnosis of selected ophthalmic tumors in which the diagnosis cannot be determined by routine diagnostic techniques.

摘要:

We treated 12 patients who had essential blepharospasm with brow and eyelid injections of botulinum toxin. The eyelid injections were kept constant while varying doses were used in the brow. The duration of the effect of the toxin was longer and the degree of improvement greater in those patients receiving more than 20 U in the brow than in those receiving less than 20 U. However, the degree of improvement in spasm intensity in those patients receiving greater than 20 U was similar. Ptosis occurred in seven patients. No systemic side effects were noted.

摘要:

A 72-year-old man had secondary orbital involvement with dermatofibrosarcoma protuberans 36 years after removal of the initial tumor on his forehead. In addition, multiple bilateral inferior orbital masses were present, which on pathologic examination proved to be reactive lymphoid hyperplasia. Serum immunoelectrophoresis revealed polyclonal elevations of IgG and IgA. Dermatofibrosarcoma protuberans is part of the spectrum of fibrohistiocytic tumors that also includes atypical fibroxanthoma and benign and malignant fibrous histiocytoma. The exact cell of origin of dermatofibrosarcoma protuberans is controversial, though immunohistochemical study of our specimen supports the fibroblast. The coexistence of this rare orbital tumor with noncontiguous reactive lymphoid hyperplasia is unique, and points out the fact that multiple orbital masses may indicate more than one underlying disease process.

摘要:

Leiomyosarcoma has been rarely encountered in the orbit. Leiomyosarcoma may arise as a primary tumor in the orbit, metastasize from distant sites to the orbit, extend into the orbit from the paranasal sinuses, or appear after radiation therapy to the orbit. The 43-year-old female patient described in this paper underwent excision of a leiomyosarcoma in the subcutaneous tissue of the buttock. Seven years later, a leiomyosarcoma in the medial orbit was removed. The clinical course of this patient's disease was similar to that of other subcutaneous leiomyosarcomas documented in the literature. Gynecological history was remarkable for a leiomyoma of the uterus, an interesting association found in at least one other case in the literature. This was the third documented case of metastatic leiomyosarcoma in the orbit.

摘要:

Breast carcinoma metastatic to the orbit presented in four patients as a diffuse mass lesion. Clinical findings included restricted ocular motility, palpable mass, enophthalmos, and ptosis. The delay in diagnosis in three cases was due to subtle early findings, the long time interval from the primary breast lesion, lack of other metastases, and, in each of the four cases, the patient's reluctance to disclose any history of breast disease. Pathologic examination of the orbital breast metastases revealed two types: an adenocarcinomatous pattern with nests of pleomorphic malignant appearing cells and a histiocytoid variant with bland, large cells similar to histiocytes.
