BRITTON DEYNARD, M.D., New York* DEFINITION. Any enlargement of the thyroid gland containing a cyst. CLASSIFICATION. Clinically we meet single or multiple cysts. Where vessels predominate in morbid action we have vesicular or caver- nous cysts. They contain sometimes pure blood. Where connective tissue increases, fibroid development takes place; produc- ing the fibro-cystic formations whose con- tents in appearance vary from grumous to gray-looking serum. Calcareous degeneration takes place in the cyst wall or septae when multiple, but this is rare. As exophthalmic goitre, or Graves' disease, may accompany this and every form of thyroid enlargement, it is most probable they are only different manifestations of one and the same dis- ease. ETIOLOGY. The cause, like that of goitre itself, is an unsettled problem. It is found in the frozen North and under the tropics. Humboldt mentions its prevalence in South America among those of most varied environments, as to soil and climate, and a recent traveler, Vincent, alludes to its prevalence there, particularly among the Venezuelians. Over sixty per cent, of the inhabitants of the Indian Punjaub are said to be affected with goitre. That it is due to a high percentage of mag- nesian lime in solution in the water can- not be maintained. That it may be a mycosis there is some reason to believe. Klebs suggests organisms. He sees a relationship in changes taking place in the enlarged spleen of intermittent, and goitre. No inflamatory change in vessels, but a lessened resistance pressure of vessel walls of spleen and thyroid gland. PATHOLOGY. The thyroid is a vascular, ductless, and true epithelial gland. There takes place a defective maintenance of structure, increase of fluids and organizable products, and oozing of coloring matter. Colloid metamorphosis occurs in cell contents and then it liquifies. Virchow thinks that colloid of this gland commences in the free fluid of its follicles after having been let loose by the destruction of the cells. Cell walls atrophy and connective tissue forms capsule or capsules of cyst or cysts. Hemmorrhage occurs which colors contents of cysts, and hence fluid is generally grumous in appearance. Under the microscope are seen detritus, fatty de- generation cells, and cholesterine. Al- bumen is always found in cyst contents, and according to Conheim1, the thyroid is the typical seat for the development of the so-called alkali-abumen; albumnose and meucin. Cysts may develop in cases where little colloid degeneration is seen. instructor Post Graduate Medical School, Assis- tant Surgeon Manhattan Eye and Ear Hospital.

The symptoms depend on the presence ■of tumor and the pressure made by it. The most common fibro-cystic have ir- regular outlines, firm consistency, and fluctuating cysts. Dyspnoea is present generally, but size of growth does not always determine its extent. Pressure on veins may lead to passive hypersemia of the brain and tidal tinnitus is sometimes present, anaemia constant and prominence of eyes sometimes. It is generally seen in young women, and a hypodermic syringe, used as an exploring needle and aspirator, makes diagnosis easy. The presence of so marked an enlargement over the thyroid region and such an as- semblage of symptoms could only be con- founded with an aneurism or malignant growth. The former does not move vertically during deglutition and after -cysts have formed in cancers, evidence of the disease in adjoining glands would present itself. TREATMENT. The methods used in the following cases will best elucidate the principles underlying plan of treatment adopted, and found effective. Case I. Miss 0., get 30, housekeeper, was seen in June, 1889, with large globu- lar growth in median line of neck over thyroid region, and extending on both sides as far as the carotid vessels. Patient was lymphatic temperament, ansemic and suffering from dyspnoea. A hypodermic needle passed through the centre of the enlargement revealed the presence of a fluid cavity, and the syringe used as an aspirator brought out some dark-looking fluid which did not coagulate on exposure to the air. Tr. Iodine, which in the experience of the writer had been so effec- tive in the treatment of simple hyperplasia of the thyroid was injected (10 m.) into the lateral lobes several times during the summer, and while it lessened the lateral lobes in size, it did not relieve the dyspnoea or reduce the central enlargement. In October following, a seton passed through the cyst entrance and exit about two inches apart caused considerable reaction; temperature 103.° At the end of ten days, patient was put to bed, and suppuration around cord enabled one to pass a small trocar and canula. Through canula re- tained in position, injection of sol. acid carbolic was used frequently. At the end of ten days, constitutional disturbance had ceased. The seton and canula were removed and a drainage tube introduced. This treatment was kept up for six weeks when tube was removed. The discharge continued of pus for seven weeks and it was feared a permanent fistula would re- sult, but healing in a month occurred. The cyst prominence almost entirely dis- appeared, the dyspnoea was relieved, but the patient passed out of sight and there- fore the ultimate result cannot be stated. Case II. Miss S., student, set 22, brunette, family history good, presented herself July, 1890, with large growth over thyroid region more marked on right side. Patient had pallor and dyspnoea. It was stated cyst had been tapped and quickly refilled. From the irregular form, hard and heavy fibroid formations were suspected and afterwards confirmed. Drew off with the aspirator a tumbler full of grumous-looking fluid. At the end of a week it was refilled. Cocaine was in- jected under the integument over the cyst, and an incision severing tissues made. When the dark-colored thy- roid gland -was exposed a double corded silk seton was passed and repassed through the cyst wall. Entrance and exit a half inch apart. The ends of the . seton strands were separated and tied about six millimeters apart on either side with a view to cut off circulation in enclosed space. Inflammatory symptoms followed and temperature went up to 104° on the third day. The space enclosed was now divided; no hemorrhage following. The phenic acid solution for irrigation was used and temperature fell to normal gradually during'two days. The opening was kept up with two large drainage tubes, and the cyst cavity healed up, after four weeks, from the bottom. The dyspnoea and central enlarge- ment disappeared, but the lateral lobes con- tinued hypertrophied. Tr. iodine injec- tions subsequently reduced the size of the lateral lobes somewhat, but whether from infrequency (5 times) or from inefficiency I am unable to state. At the present time, over the situation occupied by cyst, de- pression appears and patient is pleased with result of treatment. 4 Case III. Miss G., aet. 28, dressmaker, active and intellectual, applied in October, 1891, for relief from deformity and dyspnoea. Patient was cachectic, anaemic and the eyes prominent. There was a large growth over the region of the thy- roid isthmus. Patient had been treated for three years off and on with the iodides. A hypodermic needle determined the con- tents of a cavity in growth and the con- tents shown by aspirating consisted of a liquid resembling serum and blood. After a hypodermic of cocaine as in the last case, a bistoury was used and cyst opened as if it were an abscess. The hemorrhage was profuse, but venous in character, and easily controlled by packing the cyst cavity with borated cotton and compress. The second day this was removed, and the bleeding which was free quite ceased after applying saturated solution chromic acid to cavity and repacking. There were no constitutional symptoms and my associ- ate Dr. J. H. McCullough, who assisted and attended to subsequent treatment, informs me that suppuration hastened by poultices took place, and healing as desired. I saw the patient one year after. The growth was not apparent; the patient much improved in health and grateful for treatment. Case IV. Miss H., jet. 20; student; was first seen June, 1888, with simple parenchymatous goitre of medium dimen- sions. A hypodermic of tr. iodine in six weeks reduced the thyroid to normal size. In October, 1891, patient presented her- self with large growth over the thyroid region. She was very anaemic, eyes pro- truding, and had dyspnoea and stupidity. The presence of a liquid cavity was deter- mined with the hypodermic syringe, and its contents shown to resemble grumous fluid. Cocaine was used and an opening made down to the cyst wall. This was opened with bistoury. Hemorrhage was copious, but with fingers in wound some- what under control. Adjoining cysts to the one opened were determined upon and septas severed. Packing with cotton and compress stopped bleeding. The second day chromic acid was applied to the inside of cavity repacked. No constitutional disturbance followed and my associate Dr. J. H. McCullough, who was present and attended subsequently,reports no incidents of importance. I saw patient one year after and the central enlargement had disappeared. There was no prominence of eyes nor dyspnoea. The general health of the patient was greatly improved. The lateral lobes were somewhat enlarged, but the results were satisfactory to the patient. CONCLUSION. It is quite unnecessary to state that the dangers of such treatment was made known to the patients. They were under- taken as a duty rather than as an antici- pated pleasure. All the precautions that go along with modern surgery: cleanliness, etc., were observed as far as practical. Prof. Depuis reports cases treated with trocar, canula, and tr. iodine. Canulaleft no wound while healing. Billroth reports a death from suppuration and septicaemia after injection of alcohol. With an open wound there is less danger from septicae- mia, and it is more under control. In- cision is to be preferred to excision of the cyst owing to difficulties attending the operation and dangers following, such as shock, etc. Removal of gland is con- demned by more recent writers owing to the danger of a development of a con- dition first described by Sir Win. Gull, and afterwards by Dr. Ord named myxoedema. A state in which meucin is developed in the connective tissue, and higher phychological centres become less responsive. This is, doubtless, the cachexia strumipriva of the German writers. The few cases of myxoedema seen by the writer resembled forms of cretinism. Cutting out a portion of the isthmus of the thyroid, first practiced by Sidney Jones, is said to be efficient treat- ment, but in those cases the anatomical identity of isthmus could not be recog- nized, owing to degeneration malforma- tions. The hemorrhage is free, but except in haemophilia under eontrol with the packing and caustic as described. That there is danger from air and blood clot entering the veins there is no doubt, but in all surgery involving veins of the neck the risk can be lessened by pressure below the seat of incision. It is said that that those who follow the service of the gynecologist or the ophthalmologist learn how much traumatism the abdomen or the eye can stand, and it is hoped from a perusal of this paper some reader may better estimate how much meddling the cyst of the thyroid in some cases will stand with benefit to their possessors.
