This is a clinicopathologic study of 115 lacrimal sac neoplasms in adults (mean 52 years). The most common presenting signs and symptoms were epiphora (53%), recurrent dacryocystitis (38%), and/or lacrimal sac mass (36%). The tumors were divided into epithelial (82 cases) and nonepithelial (33 cases) neoplasms. Benign epithelial tumors included squamous and transitional cell papillomas (32), oncocytomas (4), and benign mixed tumors (2). The malignant epithelial neoplasms included squamous cell carcinoma (22), transitional cell carcinoma (5), adenocarcinoma (4), mucoepidermoid (3), adenoid cystic (3), and poorly differentiated carcinoma (1). The nonepithelial tumors consisted of fibrous histiocytoma (13), lymphoid lesions (10), malignant melanoma (6), hemangiopericytoma (1), lipoma (1), granulocytic sarcoma (1), and neurofibroma (1). Review of the literature, including our own series, discloses a 55% malignancy rate for tumors originating in the lacrimal sac. Malignant epithelial neoplasms, especially invasive transitional cell carcinoma, often recur locally and can metastasize and be fatal. Epithelial malignancies tend to grow along the epithelium of the lacrimal drainage system, and thus cure is dependent on a wide surgical excision of the tumor and of the entire lacrimal drainage system (canaliculi, sac, and nasolacrimal duct) combined with a lateral rhinostomy and radiation therapy.

Carcinomas of the exocrine pancreas respond poorly to most chemotherapy regimens. Recently continuous infusional 5-fluorouracil (200 mg m-(2)day-1) with 3 weekly cisplatin (60 mg m-2) and epirubicin (50 mg m-2) (the ECF regimen) has proven to be an active regimen in gastric and breast cancer and consequently worthy of further study in pancreatic cancer. Thirty-five patients were treated with the ECF regimen as above, of whom 29 were evaluable for response and 32 were evaluable for toxicity. The mean age was 59 years (range 37-75). Sixteen patients had locally advanced disease at presentation and 19 had metastases. Objective tumour responses were documented in five (17.3%) patients who achieved a partial response; in 18 (62%) patients there were no change and six (20.7%) patients progressed on therapy. Patients with either stable disease or partial response had a significantly improved overall survival (median = 253 days) compared with patients who progressed (median = 170 days; P = 0.01). Grade 3/4 (WHO) toxicity (all cycles) included alopecia in 18 (56%) patients, nausea/vomiting in eight (25%) stomatitis in three (9%) and diarrhoea in seven (22%) patients, with rhinorrhoea and excessive lacrimation in one patient each. Neutropenic sepsis occurred in 13 cycles in ten patients, and there was one toxic death due to sepsis. There were eight other episodes of non-neutropenic sepsis requiring hospital admission. Fourteen patients (40%) experienced complications with their Hickman lines, including thrombotic episodes (six patients) or their line falling out (five patients). ECF can prolong survival in patients with locally advanced or metastatic pancreatic cancer who demonstrate a response or stabilisation of their disease. However, this is associated with considerable toxicity.

Ethmoid sinus adenocarcinoma with orbital invasion is distinctly uncommon. This case presented with epiphora, whereas proptosis and decreased ocular motility were later signs. Treatment was delayed for 4 months, while misdiagnoses like dacryocystitis and thyroid eye disease were entertained. Even an incisional biopsy was not sufficient for a conclusive diagnosis and adenomatous differentiation was only present in a small proportion of tissue available after an excisional attempt. The aggressive behaviour including this patient's death of metastatic disease, underlines the importance of considering secondary invasion from a sino-nasal malignancy in uncharacteristic orbital disease.

The authors report a 54-year-old woman with papillary thyroid carcinoma (Lindsay type, pT2 N0 M1) with pulmonary metastases. After a total thyroidectomy, a series of 3 radioiodine therapies were performed with a cumulative dose of 700 mCi I-131. After termination of the therapy, the patient was initially without complaints, but approximately 6 months later, epiphora was noted, first only of the right eye and eventually of both eyes. A whole-body I-131 scan performed 1 year after final radioiodine therapy showed atypical tracer accumulation in both medial orbital regions. This finding was new compared with the scan that was done 1 year before. Dacryocystography revealed bilateral occlusion of the lacrimal drainage system. A review of the literature shows that epiphora and lacrimal duct alterations are rarely investigated and potentially underestimated side effects after high-dose radioiodine therapy.

A 48-year-old woman presented with a 5-month history of unilateral epiphora and progressive growth of a left-sided medial canthus mass. CT revealed a nonenhancing soft tissue mass of the left lacrimal sac with widening and erosion of the nasolacrimal canal. The tumor was resected and pathologically confirmed to be malignant melanoma. Despite wide resection and adjuvant radiotherapy, the patient developed metastases to the chest wall. The patient currently is receiving combined immunotherapy and chemotherapy. The clinical course and treatment strategies are reviewed for this highly aggressive and rare neoplasm.

A 68-year-old woman presented with a 10-month history of right-sided epiphora, bloody tears, and medial canthal mass. Computed tomography revealed a soft tissue mass of the right lacrimal sac with widening of the bony nasolacrimal canal. External dacryocystorhinostomy with incisional biopsy confirmed the diagnosis of malignant melanoma. After staging, further therapy included orbital exenteration, lateral rhinotomy with en bloc resection of the lacrimal drainage apparatus, and adjuvant radioimmunotherapy. One year after surgery, no evidence of local recurrence or metastatic disease could be detected.

The purpose of this study was to determine the characteristics of primary diffuse large B-cell lymphoma (DLBCL) of the lacrimal sac. A 77-year-old man had epiphora of the right eye for three years. After visiting five clinics and hospitals, he was referred to our hospital, and the preoperative magnetic resonance imaging findings suggested a lacrimal sac mass. Dacryocysteography showed an obstruction of the right nasolacrimal duct, so we performed dacryocystectomy. After a histopathologic examination of the specimen, the patient was diagnosed with a DLBCL. Positron emission tomography scanning excluded metastases, and the final diagnosis was made of a primary DLBCL of the right lacrimal sac. He underwent radiotherapy with 30.6 Gray in total to the right lacrimal sac. After radiotherapy, no recurrence has been observed anywhere in his body for one year. Although a malignant lymphoma of the lacrimal sac is rare, clinicians should consider a primary malignant lymphoma in the differential diagnosis in patients with chronic dacryocystitis.

Oncocytic adenocarcinoma of the orbit is a rare tumor, with 1 case of nonlacrimal sac, nonlacrimal gland origin, and a poor outcome previously reported. An 85-year-old man with a 2-month history of left-sided epiphora, enlarging eyelid nodules, and diplopia in left gaze was found on imaging to have a poorly circumscribed, nodular mass of uniform radiodensity in the inferomedial orbit. Incisional biopsy revealed morphologic and immunohistochemical features of oncocytic adenocarcinoma with origin in the caruncle suspected, and CT of the neck, chest, abdomen, and pelvis showed no metastases or remote primary tumor source. Based on multidisciplinary consensus, orbital exenteration with adjuvant radiation therapy was performed, and there was no evidence of residual or recurrent tumor 2 years after treatment.

Tumors of the lacrimal sac are rare but their recognition and early management are imperative, as they are locally invasive and potentially life-threatening. Because of their rarity, large clinical studies with statistically significant data on the natural course, management, and prognosis of these neoplasms are unavailable. Current practices are therefore based on a few case series and a small number of isolated case reports. Most tumors are primary and of epithelial origin (60-94%), of which 55% are malignant. Lacrimal sac tumors typically present with epiphora and a palpable mass over the medial canthus and are thus often erroneously diagnosed as chronic dacryocystitis. A full history with clinical and diagnostic workup is essential to plan treatment, which is often multi-disciplinary. Statistically significant associations have been shown with higher tumor staging and size with increased metastatic risk and lower survival rates. Management usually involves complete surgical resection with adjuvant radiotherapy and/or chemotherapy for malignant lesions. Long-term follow-up is required, as recurrences and metastases can occur many years after initial treatment.

Presented is a rare case of basaloid adenocarcinoma of the lacrimal sac. Low grade features of this malignancy permitted a conservative surgical approach to maximize functional and cosmetic outcomes. This is retrospective case description of a single 77-year-old-female patient who underwent a dacryocystorhinostomy with silicone tubes at an outside hospital for epiphora, but was referred to the Wills Eye Hospital Oculoplastics Department for a lacrimal sac biopsy showing low-grade carcinoma with basaloid features. She was treated with complete excision of the mass, common canaliculus and distal canaliculi, and the nasolacrimal duct. The associated maxillary, lacrimal, and ethmoidal bones were similarly excised. Frozen sections were sent of the surrounding periosteum, orbital fat, nasal and sinus mucosa, and soft tissues, and all were negative. Reconstruction of the lacrimal system was performed with silicone tube intubation and the defect was closed with large glabellar and mid-facial flaps. One year post-operatively she maintained a normal ocular examination, and her eyelids and silicone tubes were well positioned. Systemic evaluation remained unrevealing. Basaloid adenocarcinoma of the lacrimal sac is relatively rare, and we highlight the role of a more conservative surgical intervention given the high rates of survival and low incidence of progression to metastatic disease when treating this rare malignancy.
