Successful surgical treatment of thoracic multiorgan lymphangiomatosis

Clinical features and outcomes of male patients with lymphangioleiomyomatosis: A review

BACKGROUND

Lymphangioleiomyomatosis (LAM) is a rare disease involving multiple systems, which is divided into sporadic LAM (S-LAM) and tuberous sclerosis complex-LAM, mostly affecting women who are in childbearing age stage. Data on male patients are limited and scattered. Therefore, it is necessary to conduct a systematic review to investigate the clinical features, diagnosis, treatment, and outcomes of LAM in male.

METHODS

We performed a literature review by searching for all the published reported cases of LAM in male during the past 35 years (April 1986-October 2021).

RESULTS

36 male patients described in 26 references were included in this article. The median age of onset was 34 years (interquartile range: 1-79). The most common initial manifestations were cough, dyspnea, respite, and hemoptysis, with pulmonary complications such as pneumothorax and chylothorax. Five patients (13.9%) were asymptomatic at admission. Nearly half of the 36 male patients had thin-walled air-filled cysts that were visible throughout both lungs. Considering the abovementioned atypical clinical features, misdiagnosis was committed in 8 patients (22.2%). In addition, patients with tuberous sclerosis complex lymphangioleiomyomatosis often have no pulmonary manifestations at onset but present multiple extrapulmonary manifestations and have higher rates of renal angiomyolipomas than patients with S-LAM (P < 0.01). Eventually, 4 patients with S-LAM eventually died.

CONCLUSION

Physicians should increase the awareness of LAM in male. Early monitoring of various systems should be recommended to ensure early management and active follow-up. Tuberous sclerosis complex patients should immediately be tracked for the onset of LAM disease to improve prognosis.

Lymphangiomatosis: clinical overview

"Lymphangiomatosis" is a general term for excessive growth of aberrant lymphatic vessels. The impact of lymphangiomatosis can be devastating due to osteolysis and/or multi-organ involvement. The disorders are heterogeneous, and treatment is dependent upon disease location and symptoms. Most reports are single cases or small case series, predominantly in the orthopedic and radiologic literature. Basic research focused on lymphatic disorders may translate into new therapies for these disorders.

A Pleural Effusion with an Unusual Cause

A 35-year-old presented with an incidental finding of a small left pleural effusion on a routine chest radiograph. A diagnostic pleurocentesis revealed a chylous effusion. CT showed a small left pleural effusion, multiple small pulmonary nodules and thickened interstitial lines in the right lung. Video-assisted thoracoscopic biopsy of the right lung revealed features consistent with diffuse pulmonary lymphangiomatosis.
