Adenoid cystic carcinoma of the superonasal conjunctival fornix

The case of a 32-year-old female with a mass in the superonasal conjunctival fornix is described. Histological examination revealed an adenoid cystic carcinoma, which we consider to be most likely derived from an accessory lacrimal gland. The clinical presentation, histological features, management and follow-up are described. A literature review of orbital adenoid cystic carcinoma arising outside the main lacrimal gland is presented.

Adenoid cystic carcinoma presenting as an orbital apex syndrome

Adenoid cystic carcinomas (cylindromas) are distinctive neoplasms characterized by slow growth, perineural spread, extensive local invasion, frequent recurrence, and high mortality. A case of paranasal sinus adenoid cystic carcinoma presenting as an orbital apex syndrome is described.     

An atypical presentation of adenoid cystic carcinoma of the lacrimal gland

PURPOSE: To report a case of lacrimal gland adenoid cystic carcinoma (ACC) with an atypical initial presentation and to postulate an anatomical explanation for this unusual biologic behavior. DESIGN: Interventional case report. METHODS: An orbital magnetic resonance imaging study of a 58-year-old man who complained of progressive diplopia and orbital discomfort disclosed a soft tissue mass in the left cavernous sinus and orbital apex. The left lacrimal gland and the contiguous bone appeared normal. RESULTS: Biopsy of the intracranial mass revealed ACC of unknown origin which was judged to be unresectable. He underwent two cycles of intraarterial cytoreductive chemotherapy followed by a left medial maxillectomy with sphenoethmoidectomy, orbital exenteration, and chemoradiation. ACC tumor cells were identified in nerve fiber bundles surrounding and within the lacrimal gland. CONCLUSIONS: In patients presenting with an infiltrative mass in the cavernous sinus or orbital apex, metastatic disease from an occult lacrimal gland primary should be considered, even with a normal-appearing lacrimal gland.     

An unusual clinical course of adenoid cystic carcinoma of the lacrimal gland

The case of a 25-year-old woman with adenoid cystic carcinoma of the lacrimal gland is reported. Her complaints, including pain and localized swelling, first started six years earlier. She was diagnosed elsewhere as orbital pseudotumor based on clinical and computed tomographic features and was prescribed oral corticosteroids. The regimen completely relieved her signs and symptoms, which regularly recurred in the ensuing years. When she finally presented with rapidly worsening proptosis and pain, she underwent incisional biopsy followed by exenteration and 6000 cGy of radiotherapy. This patient is a rare example of adenoid cystic carcinoma of the lacrimal gland with an atypical clinical course of long duration during which corticosteroids completely suppressed the clinical signs and symptoms.

Adenoid cystic carcinoma arising in the inferior orbit without evidence of lacrimal gland involvement

A 60-year-old woman sought treatment for right orbital fullness and intermittent headache. CT revealed an inferior orbital mass along the inferior rectus muscle. Incisional biopsy revealed an adenoid cystic carcinoma. Orbital exenteration followed by concurrent radiotherapy and chemotherapy was performed. The lacrimal gland was uninvolved by tumor microscopically. Although rare, adenoid cystic carcinoma must be considered in the differential diagnosis of an orbital tumor, because the unusual location of an orbital adenoid cystic carcinoma may make its early detection difficult.     

Adenoid cystic carcinoma of the lacrimal gland: report of two cases and literature review

The adenoid cystic carcinoma of the lacrimal gland is a rare malignant orbital tumour, which has a generally poor prognosis. The therapy for adenoid cystic carcinoma of the lacrimal gland remains controversial. We present two cases of patients with adenoid cystic carcinoma of the lacrimal gland, who were treated with radical surgery in combination with radiotherapy. The therapeutic results are discussed with reference to relevant literature reports.     

Adenoid cystic carcinoma with orbital and cranial metastases: case report.

Adenoid cystic carcinoma of the paranasal sinuses was demonstrated in a patient who subsequently developed a metastatic lesion to both orbits resulting in total blindness. While there are reports of extension of adenoid cystic carcinoma of the lacrimal gland to the adjacent orbit, this patient is an example of orbital extension of an adenoid cystic carcinoma of minor salivary gland originating in a paranasal sinus. The frequency and classification of this tumor also is reviewed.     

Two cases of orbital adenocarcinoma treated with heavy charged carbon particle irradiation

Background Orbital adenocarcinoma is a relatively rare, primary orbital malignant epithelial tumor, and shares the poor prognosis of orbital adenoid cystic carcinoma. We report the cases of two patients with orbital adenocarcinoma who were treated with heavy charged carbon particle irradiation and followed up for more 6 years.Method Two patients with orbital adenocarcinoma, 62 and 74 years old, received 57.6 GyE of heavy charged particle irradiation therapy.Results In both cases, the size of the tumor gradually decreased after carbon ion irradiation therapy. No recurrences or metastasis of the tumor were found for more than 6 years.Conclusion Orbital adenocarcinoma has a poor prognosis in general. Two patients with orbital adenocarcinoma were treated with heavy charged carbon particle irradiation therapy and had a relatively good outcome and good prognosis. We believe that heavy charged carbon particle irradiation therapy is a promising therapy for orbital adenoid cystic carcinoma and adenocarcinoma.     

Primary cutaneous adenoid cystic carcinoma of the eyelid

PURPOSE: To report a case of primary cutaneous adenoid cystic carcinoma involving the eyelid. METHODS: We examined a 70-year-old woman with an 18-month history of a gradually enlarging, blue-colored mass in the medial third of the right upper eyelid. Excisional biopsy and additional resection of the medially infiltrated margin resulted in tumor-free edges. Superior cervical and orbital evaluations were performed. RESULTS: Histopathologic evaluation revealed a primary cutaneous adenoid cystic carcinoma. No gland pathology was documented. No tumor recurrence has been noted. CONCLUSION: Primary cutaneous adenoid cystic carcinoma, an uncommon tumor of the skin, should be added to the differential diagnosis of eyelid tumors.     

Primary adenoid cystic carcinoma: an extremely rare eyelid tumor

Cutaneous adenoid cystic carcinoma is an extremely rare clinical entity. Among the few cases reported in the literature, most had contiguous involvement from the lacrimal gland. Primary adenoid cystic carcinoma is one of the rarest eyelid tumors. The authors report a case of adenoid cystic carcinoma arising from the lower eyelid.     

Orbital cysts of childhood--classification, clinical features, and management

There is little in the literature about the clinical spectrum of orbital cysts of childhood and no comprehensive classification has been proposed. The authors propose a classification of orbital cysts of childhood and review their clinical features, pathology, and management. The major categories in the classification include cysts of surface epithelium, teratomatous cysts, neural cysts, secondary cysts, inflammatory cysts, and noncystic lesions with cystic component. Cysts of the surface epithelium are further divided into simple epithelial cyst (epidermal, conjunctival, respiratory, and apocrine gland), and dermoid cyst (epidermal and conjunctival). Epidermal dermoid cyst (dermoid) is by far the most common orbital cystic lesion in children, accounting for over 40% of all orbital lesions of childhood and for 89% of all orbital cystic lesions of childhood that come to biopsy or surgical removal. Neural cysts include those associated with ocular maldevelopment (congenital cystic eye and colobomatous cyst) and those associated with brain and meningeal tissue (cephalocele and optic nerve meningocele). The most important secondary cyst is mucocele that can occur in children with cystic fibrosis. Inflammatory cysts are generally due to parasitic infestations and are more common in tropical areas of the world. Noncystic lesions that can have a cystic component include adenoid cystic carcinoma, rhabdomyosarcoma, lymphangioma, and others. Each type of cyst has rather characteristic, but not pathognomonic, clinical features. Computed tomography and magnetic resonance imaging can help differentiate a cystic lesion from a solid tumor, suggest the type of cyst, and help in planning management. The pathology varies with the cells that line the cyst and with the inflammatory agent. Management varies from local excision to observation, depending on the location and type of cyst. Orbital cysts of childhood can be classified into categories, based mainly on their histopathology. The clinical, radiologic, and histopathologic features can be correlated with the classification in order to better evaluate a child with a cystic lesion in the orbit.     

Plaque radiotherapy for selected orbital malignancies: preliminary observations: the 2002 Montgomery Lecture,part 2

PURPOSE: To describe the principles and preliminary results of plaque brachytherapy for selected orbital malignancies. METHODS: A custom-designed Iodine-125 plaque, designed to deliver a target dose of 50 Gray, was placed surgically in the region from which an orbital malignancy was partially resected. The mean dose to the target area was 50 Gray. The initial and follow-up patient data were reviewed. RESULTS: Of the 8 patients, the diagnosis was adenoid cystic carcinoma of the lacrimal gland (4 cases), orbital invasion by basal cell carcinoma (2), orbital extension of conjunctival melanoma (1), and metastatic carcinoma (1). Of the 4 with adenoid cystic carcinoma, there was microscopic residual tumor after excision and orbital exenteration was considered. Three have tumor control with follow-up of 1, 3, and 6 years. One patient required exenteration for recurrence separate from the field of brachytherapy and is free of tumor after 10 years. All 4 patients are alive and well with tumor control. Of the 2 patients with orbital extension of basal cell carcinoma, tumor control without recurrence has been achieved in both after 2 years. The patient with orbital metastasis responded to plaque radiotherapy, with no orbital recurrence, but died of systemic metastasis. The patient with orbital melanoma had local orbital recurrence separate from the area of irradiation and is currently being treated for systemic metastasis. CONCLUSIONS: Based on preliminary observations, plaque radiotherapy appears to be a reasonable alternative to exenteration and external irradiation for selected orbital malignancies.

泪腺腺样囊性癌是泪腺最常见的恶性上皮肿瘤,具有易复发、易转移及预后差的特点,目前临床治疗方式主要有手术切除、放疗、化疗等,但其生存率仍低。因此,进一步研究泪腺腺样囊性癌的发病机制和寻找泪腺腺样囊性癌的生物标志物尤为迫切。本文将对泪腺腺样囊性癌的生物标志物的研究进展作一综述。     

Choroidal metastasis from adenoid cystic carcinoma of the lung

PURPOSE: We report a case of a choroidal metastasis from an adenoid cystic carcinoma of the lung.Interventional case report. DESIGN: A 40-year old man, 9 months' status postresection of a bronchial adenoid cystic carcinoma, was diagnosed by clinical evaluation and fine-needle aspiration biopsy and treated with palladium-103 ophthalmic plaque brachytherapy. RESULTS: This unusual patient with uveal metastasis from adenoid cystic carcinoma presented with decreased vision in the right eye and a diaphanous amelanotic choroidal tumor in the superotemporal macula. Ultrasound revealed a dome-shaped tumor that measured 4.0 mm in apical height and 11 x 10 mm in basal diameter. Fluorescein angiography revealed a double circulation and late intense subretinal fluorescence. Plaque brachytherapy provided local control and preservation of the eye. CONCLUSION: Bronchogenic adenoid cystic carcinoma can metastasize to the choroid.

Adenoid cystic carcinoma of the lacrimal gland]

A 38-year-old female presented with a left-sided peripheral N. VI-paresis and negative neuroradiologic work-up. After one year she developed an incomplete N. III paresis, numbness of her face correlating to N. V1 and V2, reduced lacrimal secretion as well as a palpable mass at the lateral orbital rim. Magnetic resonance imaging revealed an orbital tumor extending into the cavernous sinus. Biopsy disclosed an adenoid cystic carcinoma of the lacrimal gland with basaloid, cribriform and tubular pattern. Therefore, an exenteration with postoperative radiation therapy was performed. Immunohistochemical findings included positive reactions for keratin (KL-1 and AE 1 + 3), Vimentin and Egp 34. By determination of Ki 67 the proliferative activity of the tumor was found to be 15%. Our case report demonstrates that even in absence of an exophthalmus or pain a malignant orbital tumor may be assumed as the underlying cause for a combined monolateral oculomotor and trigeminal paresis. Immunohistochemical results support the notion, that the adenoid cystic carcinoma of the lacrimal gland may arise from precursor cells of the terminal duct system.
