Disappearing nodules: spontaneously regressing pulmonary amyloidosis

Spontaneously disappearing lumbar disc protrusion.

Spontaneous disappearance of a herniated lumbar disc is known to occur. This case study describes a 45-year-old patient whose symptoms of lumbar radiculopathy resolved and follow-up imaging showed complete disappearance of the disc prolapse. This phenomenon strengthens the role of conservative treatment in the management of lumbar disc protrusions.

Animal Models Spontaneously Regressing Malignant Melanomas

Human melanoma is the fastest growing cancer currently in USA and worldwide. Melanoma accounts for 5% of all skin cancers but 71% of all skin cancer deaths. The risk for melanoma has steadly increased since 1935 when the risk was 1:1,500. Today one in 74 people are diagnosed with melanoma. The mechanism for melanoma initiation is unknown and no significant advances in medical therapies (surviva...

Pulmonary nodules due to reactive systemic amyloidosis (AA) in Crohn's disease.

Multiple nodules of AA (reactive systemic) amyloid were identified at necropsy in the lungs of a patient with Crohn's disease. No other organs were involved. Nodular pulmonary amyloidosis is usually caused by deposition of AL (primary) amyloid.

Pulmonary and tracheobronchial amyloidosis.

Amyloidosis is a collection of diseases in which different proteins are deposited as insoluble beta-pleated sheets, disrupting organ function. Each precursor protein induces a separate spectrum of organ involvement, and different disease manifestations within the lung. Although autopsy data often demonstrate amyloid deposits in various compartments of the lung, few of the pathologic findings ar...
