CLINICAL ABSTRACT:

HISTORY: Entry was made to the hospital on May 27th, 1955, with com­plaints of sudden onset three months previously of a growth in the neck. The local physician had found a BHR of plus 50 in March, 1955, and placed her on Lugol's solution and Thiouracil, but without benefi t , Subsequently there was nervousness, wealtness , cryl.ng episodes and heat intolerance, In spite of medi cation, the mess in the neck continued to enlarge and one month before hospitalization, difficulty in eating and breathing was noticed. lbere had been no weight l oss. The pest history revealed that the patient had been a gr avida VII, para III and AB IV. The last menstrual period one weelt previous­ly had been regular.

Physical examination disclosed pulse 72 and regular, blood pressure 120/80 , respirations 16, and a prominent diffuse, S}~etrically enlarged thy­roid which moved with Sl~allowing , There ~~as no bruit.

LABOP.ATORY FINDINGS: PBI was 6, 5 micrograms, blood cholesterol mgm1. and ~m minus 30. Chest X- ray ~1as essentially normal.

For three weeks pre-operatively, propylthiouracil,lOO mgm every 8 hours and Lugol's solution was given .

SURGERY: On June 17th, 1955, a total thyroidectomy was performed, Lymph nodes were removed on the left side. In removing the thyroid, the trachea was found to be invaded.

GROSS PA'lliOLOGY: The thyroid was diffusely enlarged, hard and pinkish salmon in color.

FOLLOW-UP: lbe patient had low serum and ur inary calci um following sur gery and developed muscle cramps . She was placed on calcium supplements orally and Hytacherol. Radiation Sl!IOunting to 300 r was given to the nec!t, but was discontinued because of differer.ce in opinion regardin~ the nature of the lesion.

Patient expired on Augus t 16th, 1953.

AUTOPSY FINDINGS: Autopsy showed bilateral pleural effusion with massive left lower l obe atelectasis, hydropericardi um, chronic passive con­gestion of viscera. The l iver, spleen, pancreas and ileum, as well as per i-aortic, per ipancreatic, peri-esophageal and inguinal lymph nodes were i nvolved by tumor.

CLINICAL ABSTRACT:

December • 1958

OUTSIDE NOS. S-9305- 57, 57-A-157.

HISTORY: Onset of progressive pain occurred in the left shoulder region in August, 1957. I~ December, 1957, after a bout of influenza there was a ~relve pound weight loss over a period of three ~reeks . Entry was made to the Eden Hospital on December 15, 1957.

PHYSICAL EXAMINATION: The blood pressure was 140/90. The chest was clear. Tenderness was present in the left axillary region over the axillary portion of the third rib. There was marked clubbing of the nails of the fingers and the patient stated that this was a familial trait that had been present since chi ldhood. X-ray examination revealed destruction of the axil­lary portion of the third rib of the left side.

SURGERY: On December 16th, 1957, thoracotomy was performed lnth re­moval of the rib tumor.

GROSS PATHOLOGY: The segment of chest wall included portions of three ribs. The lower and upper ribs measured 7 em. and 12 em. in length, while the center rib was 13,5 em. in length. There was a fusiform swelling of the cen­ter rib with extension of the swelling into the intercostal muscles on each side. The region of swelling was 6.5 em. in length and ·the pleura and perio­steal tissue l~ere elevated so that the swelling was up to 3.5 em. in thick­ness and 4.5 em. wide, Section revealed granular, gray tissue with visible mucous and pale yellow areas of necrosis, The pleura overlying. the deepest part of the· tumor was intact . Ho~rever, a 0.5 em. in diameter satellite nodule was located subpleurally near the large tumor .

FOLL0l~-UP:. Postoperatively, the patient did ~7ell until December 19, 1958, when he developed hemiplegia . The following day there was substernal pressure and difficulty in breathing. On December 21st, phlebothrombosis was present in the right lower extrer.tity. The patient expired on December 21,1957.

AUTOPSY FINDINGS: ''Postmortem examination revealed that the primary neoplasm was carcinoma of the adrenal cortex·. Both glands were largely re­placed by tumor which was thought to have arisen independently in each, The absence of evidences of Cushing's syndrome, of hyperalderonateronism and the absence of Croolte' s changes in the cells of the anterior lobe of the hypophysis indicated that the neoplasm 1;as not producing hormones. The right adrenal weighed 227 grams while the left adrenal weighed 57 grams and was two- thirds replaced by tumor. No other focus of tumor lJas found. "

"The terminal events 1~ere prefaced by the develop­ment of phlebothrombosis postoperatively, and the outcome was dependent on the presence of a patent foramen ovale. Emboli from t he veins of the lower ex­tremities lodged in vessels of both ltidneys and in the brain. An embolus also occluded the artery of the posterior basilar segment of the lower lobe of the ri ht lun • "

CLINICAL ABSTRACT:

HISTORY: A tumor had -bee11 present beneath ·the right malleolus for many years. In the previous two years it had grown with some rapidity and on examination presented a mass 3.5 em. in diameter, protruding out beyond the level of the malleolus, It appeared fixed to the underlying tissue and was rather firm but somewhat elastic.

SURGERY; On October 18, 1955, the tumor of the right ankle was incom­pletely excised.

GROSS PA'l'HOUlGY: The 2.5 em. finn mass was encapsulated on its super­ior surface, but was ragged on its inferior and lateral margin. The second irregular piece of s~ilar tissue measured 1.5 em.

FOLLOW-UP: The surgeon bad planned to make a more complete re-excision of the tumor. Since it was classified as benign this was not done; For a long time the tumor did not appear to grow. However, in 1956 it gradually increased in size until it interfered \lith activity, There ~1as moderate, but not constant pain .

In June, 1957, entry was made to the hospital after the tumor bad gradually enlarged and protruded below the right external malleolus until it interfered with activity. x~rays showed bony erosion.

SECOND SURGERY .in June, 1957, showed the ~umor to be widely adherent to all bone, capsules and tendon structures and to "go through" the astragu­lus through an opening l em. in diameter. The tumor was as completely re­moved as possible, all surfaces being cleaned and scraped.

When last seen in t1ay, 1958, there was no pain in the foot, increase in size, or disability. The mild pain and discomfort did not interfere with his work. Examination showed satisfactory healing of the wound with no evi­dence of enlargement or tumor. x -rays revealed that the defects in the bone were healing and were filling in with bone and callus. There was no evidence of progression or other reaction.

CLINICAL ABSTRACT:

HIS'IDRY: Catarlh ha4 been present for many years and in October,l955, episodes of epistaxis began . On December 25th,l955, there was sudden onset of pain in the left eyebron accompa.,ied by numbness on the left side of the face . The numbness subsequently subsided,

SURGERY: On February 20th,l956, a left antral lesion was biopsied and polypoid tissue was removed from the nose as an office procedure.

GROSS PATHOLOGY: Some of the nasal fragments were polypoid and appeared friable, fibrinous, clot-like or necrotic. They varied from 0 .3 to 1.0 em. in diameter. The tissue fragments from the left antrum varied from 0.4 to 0.9 em. in diameter and were hemorrhagic and friable.

FOLLOW-UP: Following suraery, a six weeks course of X-radiation thera­PY was given. Entry was made to the Cottage Hospital in Santa Barbara in March, 1956, with complaints of anorexia and nocturnal episastric pain. Physi­cal examination revealed heptomegaly, severe anemia, pathological fracture of the right fifth finger and subcutaneous nodules of recent occurrence in the anterior thorax, anterior abdominal wall and sacral region, On April 4th, 1956 , a subcutaneous nodule of the thorax was excised and showed the same cytology as the antral tumor.

Patient was treated with a four day course of nitrogen mustard, Predni· sone and blood transfusions, The subcutaneous nodules completely disappeared and the pathologic fracture through the lytic lesion in the right fifth finger recalcified.

In the following two years, he returned six times complaining of abdomi­nal pain, back pain or new crops of subcuta.1eous nodules. Each time a course of nitrogen therapy was Qivetl and the pain would be relieved and the nodules disappear. The liver was enlarged in May, 1956, but decreased in size until terminally. Anemia ( Rbc 2.9 m ) ~ras present in ~lay, 1956. The Wbc was al · ways within normal limits until terminally when a few cells that appeared ma­lignant were in the smears.

Despite the complaint of pain in the back, repeated roentgenograms never showed bony metastases. The cervical or other superficial lymph nodes were never enlarged. The nasopharynx was clean until a small friable bleeding area was noticed on May 29th, 1958 a.,d biopsied. Terminally there was severe epis­taxis and gastro-intestinal bleeding which could not be controlled, The pa -tient expired on September 5th,l958.

AUTOPSY FINDINGS: At autopsy the enteric canal was filled with blood. ~o gross naso-pharyngeal tumor could be found, The liver was en­larged to 2200 grams and contained several soft, mushy, gray-red nodules up to 12 l!llll. in diameter. The enlarged spleen weighed 710 grams and was free of nodules. Both adrenal glands contained mushy, gray-red nodules varying from 0.3 to 3.0 em, in diameter. Bone marrow was hard, mottled pinlt-white, with­out local lytic lesions. The lungs were free of tumor,

CLINICAL ABSTRACT:

HISTORY: Continous discomfort bad been present in the lower abdomen for one week and for three weeks discomfort occurred when bending over. There had been no pregnancies.

SURGERY: ·On September 19, 1957, an ovarian tumor was biopsied. This was followed by a bilateral salpingo-oophorectomy, total hysterectomy and incidental appendectomy.

GROSS PAniOLOGY: Both ovaries were enlarged and cystic . One measured 12 x 18 x 27 em., and .the other 6 x 9 x 3 em. The external capsules were smooth, The largest cyst had a diameter and was lined by a 2.5 em. rim of gray-yellow necrotic tissue. Some of the smaller cysts were lined by light tan papillary tissue . A fe\1 had smooth thin ~1alls and contained clear gela­tinous light yellow fluid, The tubes were intact and patent.

The uterus contained a few intramural leiomyomata. The lumen of the appendix was obliterated i n its distal third,

FOLLOW-UP: On April 7, 1958, sigmoid colectomy was performed because of G.I. obstruction,

GROS·s PATHOLOGY: The 19 .5 em. segment of colon was dilated up to 16 em. in circumference in its pro1timal portion. Extending 2 em, above the distal surgical mal'gin was an annular napldn ring neoplasm encircling four-fifths of the bowel wall and extending in the dorsal ventral axis for 3.8 ems. The tumor penetl'ated the mesocolic fat and extended to the regional lymph nodes.
