Abstract:

ABSTRACT Tuberculosis of the lacrimal sac is a rare condition even in a place considered endemic to tuberculosis. It is usually suspected with either local or systemically present tubercular lesion or with a history of recurring failure of lacrimal drainage procedures. Failure to identify the ailment may have devastating consequences. We present a case of tubercular dacryocystitis and discuss its clinical spectrum. How to cite this article Gupta D, Gulati A.

Abstract:

Rhinosporidiosis is a chronic mucocutaneous granulomatous disease caused by Rhinosporidium seeberi, involving primarily the nose and nasopharynx. Very rarely, the disease can affect the lacrimal sac. Here we report a 35-year-old male patient who had rhinosporidial involvement of the nose 5 years ago, for which he underwent endoscopic nasal surgery. Five years after the excision of the nasal mass, he presented with lacrimal sac involvement. The clinical presentation and the management of lacrimal sac rhinosporidiosis are discussed here.

Abstract:

We report a case of a 60-year-old lady with sarcoidosis of the lacrimal sac. A 60-year-old female presented with redness and epiphora of the right eye and swelling that was felt only on palpation of the lacrimal sac area. Dacryocystectomy was done for the patient, and histopathology, radiology, and laboratory investigations led to the diagnosis of sarcoidosis of the lacrimal sac. There are only a few case reports of sarcoidosis of the lacrimal sac in the literature. To the best of the author’s knowledge, this is the sixth case reported regarding sarcoidosis of the lacrimal sac.

Here, we report an unusual case of lacrimal sac angiofibroma in a young male patient who initially presented with watering from right eye for 2 years and was provisionally diagnosed as a case of chronic dacryocystitis in the affected eye. Patient was advised external dacryocystorhinostomy to cure this condition. However, during routine dacryocystorhinostomy surgery, suspicious finding like highly vascularized and enlarged sac was noticed which hinted the pre

Swellings in medial canthal area in eye most often involve the lacrimal sac, the commonest aetiology being chronic dacryocystitis. Very rarely, there is a deviation in the routine diagnosis when the pathology comes out to be a lacrimal sac tumour. We report the case of a young man who presented with a medial canthal mass not extending above the medial canthal ligament. The clinical presentation was typical for a lacrimal sac mucocele, however on histopathological evaluation was diagnosed as a rare case of solitary fibrous tumour of lacrimal sac.

Abstract:

Idiopathic orbital granulomatous inflammation has been reported before, but isolated involvement of the lacrimal sac is extremely rare. The authors report the case of granulomatous inflammation in a 47-year-old-female limited to the lacrimal sac, nasolacrimal duct (NLD), and adjacent inferior meatal mucosa without any identifiable cause. She presented with rapidly progressive swelling involving the left medial canthal region and a palpable, nontender, nonregurgitant firm mass lesion extending above the medial canthus. The lacrimal irrigation was patent, and imaging showed a heterogeneous mass

Perpose. To demonstrate diagnostic value of three-dimensional computional reconstruction of the lacrimal ducts and modeling of lacrimal drainage for patients with epiphora. Material and methods. The study involved 10 patients with epiphora, parameters of lacrimal sac and nasolacrimal canal were measured, a multislice computed tomography (MSCT), MSCT with contrast and three-dimensional modeling of the passage of tears and canaliculi tests were performed. Results. Patients with lacrimal sac dilation and a slight narrowing of the proximal part of the nasolacrimal canal have no changes according t

Abstract:

Introduction: The most frequent histopathological findings in individuals having External Dacryocystorhinostomy (DCR) for acquired nasolacrimal duct obstruction are chronic inflammation and fibrosis of the lacrimal sac. Although uncommon, various pathological alterations such as infections, systemic inflammatory conditions, and neoplasms like Primary Lacrimal System Cancers, secondary invasion from neighbouring tissues, or even distant metastases, may be detected in the lacrimal sac. Aim: To study the histopathological changes of lacrimal sac and nasal mucosa in patients undergoing external DC

Abstract:

Solitary fibrous tumors (SFT) are benign neoplasms, composed of spindle-shaped cells. It has been reported in numerous locations in the body, but SFT of lacrimal sac is very rare. A 67 year old man clinically diagnosed as lacrimal sac mucocoele. During DCR, there was a yellowish mass with vascularisation on the surface. The mass was removed in-toto. Histopathology and immune-histochemisty confirmed SFT of lacrimal sac. Patient was followed up for 6 months without any recurrence.

Abstract:

Purpose: We report a case of primary small cell neuroendocrine carcinoma arising from the lacrimal sac. Case summary: A 54-year-old man presented with epiphora that had been present for 1 month. He underwent lacrimal syringe analysis of the lower punctum in the right eye, which demonstrated fluid regurgitation from the upper punctum. Computed tomography revealed a 3.0 × 3.4 × 3.0 cm mass with an ill-defined margin in the right lacrimal sac, which demonstrated invasion of the lacrimal duct and bony destruction of the inferior and medial orbital walls.

Abstract:

Oncocytoma of the lacrimal sac is an extremely rare tumor. In this report, we present the case of an 82-year-old woman who presented with swelling in the region of the lacrimal sac. Systemic examination and ophthalmic examination of both eyes were unremarkable. Computed tomography of the brain and orbits revealed a mass lesion involving the right lacrimal sac with expansion of the related nasolacrimal duct. Neither bone destruction nor tissue invasion was observed. Right external dacryocystectomy and debulking of the tumor were performed. Histopathological examination of the surgical specimen
