Generalized lymphatic anomalies and review of the current management landscape: a case report and review of the literature
Abstract
Generalized lymphatic anomaly previously known as diffuse systemic lymphangiomatosis is a rare multisystem congenital disease arising from the lymphatic system, and it is characterized by abnormal proliferation of the lymphatic channels in osseous and extraosseous tissues. It typically affects children or young adults. Although it is benign, it can be misdiagnosed as malignancy because of its diffuse and debilitating nature depending on the site of involvement. Due to its rarity, diagnosis is often delayed, leading to potential significant morbidity or mortality if vital organs are involved. Furthermore, its potential for multiorgan involvement with no curative treatment makes its management challenging. We describe a case of a 35-year-old Caucasian female, who presented with epigastric pain and was subsequently extensively investigated at multiple tertiary centers by numerous specialists for query malignancy and metabolic bone disorder following incidental computed tomography imaging findings of multiple osteolytic lesions in the axial skeleton, and low-attenuating lesions in the axilla, spleen, and mediastinum. The diagnosis was confirmed with an axillary excisional biopsy. She was clinically stable with no end organ damage. She was monitored conservatively. The case illustrates the importance of increased awareness among clinicians for this rare congenital disease to enable earlier diagnosis and to avoid unnecessary invasive investigations. Furthermore, this case…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
