The Pancoast tumor was first described by Hare in 1838 as a "tumor involving certain nerves". [2] It was not until 1924 that the tumor was described in further detail, when Henry Pancoast, a radiologist from Philadelphia, published an article in which he reported and studied many cases of apical chest tumors that all shared the same radiographic findings and associated clinical symptoms, such ...
Resection of the tumor is the ideal treatment and results in correction of hypophosphatemia (and low calcitriol levels) within hours of resection. Resolution of skeletal abnormalities may take many months. If the tumor cannot be located, begin treatment with calcitriol (1–3 μg/day) and phosphate supplementation (1–4 g/day in divided doses).

The Mayo Clinic Cancer Center is one of the oldest NCI-designated cancer centers in the United States, having first been designated in 1973. [3] The main location of the Mayo Clinic is in Rochester, MN. Campuses in Arizona and Florida opened later and became part of the Mayo Clinic Cancer Center in 2003. [4] [5]
Definitive diagnosis is made by tumor biopsy. [12] Surgery is the most common method of treating peripheral nerve sheath tumors. [11] In malignant tumors, complete resection is the only known curative treatment (with a sufficiently wide margin or even amputation to improve prognosis). [12]
A bone tumor is an abnormal growth of tissue in bone, traditionally classified as noncancerous (benign) or cancerous (malignant). [1] [4] Cancerous bone tumors usually originate from a cancer in another part of the body such as from lung, breast, thyroid, kidney and prostate. [1]
Hypertrophic osteoarthropathy is one of many distant effect disorders due to cancer, with lung cancer being the most common cause but also occurring with ovarian or adrenal malignancies. A distant effect disorder, or a paraneoplastic syndrome , affects distant areas and thus is not related to local compression or obstruction effects from the tumor.
