Abstract:
Pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma rarely occurs. It is difficult to distinguish MALT lymphomas and pre-invasive lesions according to radiological findings. We report a case of 60-year-old woman who was found to have a rapidly growing ground glass nodule (GGN) on her left lower lobe, discovered on follow-up chest computed tomography. The radiological image was pure GGN, which was compatible with a pre-invasive lesion, such as non-mucinous adenocarcinoma in situ. Wedge resection was performed and the final diagnosis was stage I MALT lymphoma. After surgery, she was doing well with no evidence of recurrence one year later. We believe a lung biopsy for rapidly growing GGN is recommended in order to confirm the pathological diagnosis.

Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...
01:15Secondary Lymphoid Organs
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
01:23Detailed Structure and Function of Lymph Nodes
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...
