Partial lipodystrophy and successful pregnancy outcome.

INTRODUCTION

Diffuse large B-cell lymphoma (DLBCL) is a prevalent subtype of non-Hodgkin lymphoma (NHL) affecting predominantly elderly individuals.

CASE DESCRIPTION: A 68-year-old man with a history of hypertension, hyperlipidaemia and a small pituitary gland tumour presented with sudden-onset binocular diplopia and right-eye blurry vision. A magnetic resonance imaging (MRI) of the brain revealed enhancing soft tissue in the right superolateral orbit inseparable from the lacrimal gland, extending medially to the right superior rectus muscle and soft tissue. Further scanning showed widespread metastasis to the bilateral retroperitoneal lymph nodes, adrenal gland, spine and lymph nodes in the neck. A biopsy of the lacrimal gland confirmed DLBCL.

CONCLUSION

Primary lacrimal gland DLBCL is a rare and delayed diagnosis that often stems from the resemblance of its clinical manifestations to more benign conditions such as dacryocystitis, dacryostenosis or mucocele. Timely recognition and accurate diagnosis are essential for initiating appropriate treatment and improving patient outcomes.

LEARNING POINTS: Lacrimal sac lymphomas represent diagnostic challenges due to their rarity, non-specific symptoms and frequent misdiagnoses as benign pathologies, hence it is crucial to include this in the differential diagnosis.Timely recognition and accurate diagnosis are important in improving outcomes for lacrimal sac lymphomas.
