The clinical details of two patients suffering from amyloid infiltration of the trachea and esophagus respectively are presented. The "amyloid tumor" in the trachea presented with dysphonia and a swelling in the lower subglottic region. Attempts at complete surgical excision of it were unsuccessful. The patient with esophageal amyloid presented acutely with
dysphagia
and features of dehydration and malnutrition. Systematized
amyloidosis
was discovered at autopsy, but no primary initiating cause for it was found. In both cases it was possible to confirm the diagnosis by electron microscopy. The current views on the composition, structure, causation and treatment of
amyloid disease
are reviewed.

We report the case of a 58-year-old woman who had a 7-year history of multiple myeloma and multiple rib fractures and who presented with
dysphagia
. She underwent thorough gastrointestinal evaluation to rule out the possibility of
amyloidosis
. Although upper gastrointestinal biopsies were negative, the rectal biopsy was characterized by extensive smudgy eosinophilic deposits in the submucosa that closely resembled amyloid, except that they were not congophilic. Fibers with serrated borders characteristic of those in elastofibroma were identified and confirmed by means of elastic stain and electron microscopy. Elastofibromatous change of the gastrointestinal tract is a rare lesion that has been reported once previously in association with gastric ulcer. This case illustrates that it may occur as a spontaneous or subclinical finding in the absence of other pathologic lesions. The close resemblance between elastofibromatous change and amyloid deposits necessitates the appropriate histochemical and ultrastructural studies.

Esophageal involvement in systemic
amyloidosis
is common. Manometric studies have been few in number and have revealed a variety of findings compatible with deposition of amyloid in myopathic as well as neuropathic patterns. This report describes a patient with primary amyloid whose esophageal dysfunction was limited to the lower esophageal sphincter, with both a hypertensive sphincter and impaired relaxation after swallows. Pharmacologic testing confirmed a mild abnormality of the inhibitory pathway to the LES with an intact excitatory pathway and sphincter muscle. This case suggests that
amyloidosis
, like idiopathic achalasia and carcinoma of the lower esophagus, can produce
dysphagia
by selective impairment of the inhibitory neural pathway to the lower esophageal sphincter.

A 67 years old man was admitted on July 1979 for nausea,
dysphagia
and rectal pain. At age 64 he had undergone radiotherapy on the lower lip for an epidermoid carcinoma. He remained then healthy. His medical history was negative with the exception of chronic bronchitis. He had never been exposed to toxic agents or drugs and had never left Europe. A few days after admission he suffered acute intestinal obstruction but at laparostomy no etiology was found. At the same time the patient complained of pain in all four limbs and he was found to have diffuse wasting of muscles, areflexia and distal sensory loss. No sign of dysautonomia was present. Physical examination was negative with the exception of a cervical lymphadenopathy. The lymph node biopsy showed an undifferentiated metastatic carcinoma. Negative investigations included: blood cells count; serum ionogram and immunoelectrophoresis; thyroid function tests; serological test for Chagas' disease. The following abnormalities were found: ESR: 55-105; CSF protein: 145 mg/100 ml and 1 cell mm3; whole blood folic acid: 1,7 mg/ml; Hbs antigen was present in blood; EMG showed evidence of denervation but motor conduction velocities were normal. By September the patient's weakness had increased and complete intestinal obstruction persisted. At oesophageal, gastric and duodenal fibroscopy no contraction was visible, and biopsies were negative. The patient died of peritonitis on October 5th, 1979. At necropsy peritonitis secondary to multiple perforation of the large bowel was found. No recurrence of the lip carcinoma or metastase or evidence of a primary carcinoma was found. Light microscopy showed no evidence of
amyloidosis
or scleroderma. Examination of the alimentary tract showed abnormalities restricted to the myenteric plexuses which varied from one level to another. In the small bowel there was hyperplasia of the smooth muscle and the myenteric plexuses were enlarged by marked proliferation of Schwann cells. Severe neuronal loss and nodules of Nageotte were also noted. Schwann cells proliferation was less marked in the stomach and large bowel. Lympho-histiocytic infiltration strictly confined to the region of the myenteric plexuses was present in oesophagus, stomach, large bowel and rectum. Mild chronic inflammatory lesions were also found in anterior and posterior spinal roots and semi-lunar ganglia. The striking feature of this case is the association of an undifferentiated carcinoma and a polyradiculoneuritis with a complete alimentary tract palsy of rapid onset, secondary to lesions restricted to the myenteric plexuses. The low folate level was insufficient to explain the neuropathy. Investigations showed no evidence of the usual causes of intestinal pseudo-obstruction: muscular, dysautonomic, toxic, plexic (idiopathic, familial, inflammatory), Chagas' disease). The clinical course, the pathological pictures of the alimentary tract and spinal roots and the association with a carcinoma suggest that our case may represent a paraneoplastic syndrome...

The authors report the clinicopathologic features of 14 cases of amyloid goiter (AG). Eleven patients were males and three females with ages ranging from 23 to 75 years (median, 54 years). Eight patients had secondary
amyloidosis
and six had primary
amyloidosis
. Nine cases were identified at autopsy. In symptomatic patients (n = 5), the clinical presentation included a nontender, rapidly enlarging neck mass with associated
dysphagia
, dyspnea or hoarseness. Clinical or laboratory evaluation failed to detect evidence of thyroid dysfunction. The histologic appearance of the thyroid predominantly consisted of diffuse amyloid deposition surrounding thyroid follicles. In two cases, a nodular pattern of amyloid deposition was seen resulting in compression and distortion of the follicular architecture. Areas of mature adipose tissue and focal lymphocytic thyroiditis with or without foreign-body type-giant cells were seen in approximately one third of the cases. Confirmation of amyloid was made by the presence of congophilia and apple-green birefringence under polarized-light microscopy. Immunohistochemical evaluation demonstrated the presence of amyloid A immunoreactivity. No Immunoreactivity was seen with calcitonin or thyroglobulin. Fine-needle aspiration may facilitate the diagnosis, as occurred in one the patients. In symptomatic patients, thyroidectomy is warranted to alleviate pressure symptoms.

Cacogeusia, being the patients' main complaint, is reported as a new symptom of
amyloidosis
, probably caused by a peripheral sensory neuropathy. A case is presented of a patient with weight loss,
dysphagia
, macroglossia and taste disturbances, due to
amyloidosis
associated with a plasma cell dyscrasia. The importance of oral manifestations in
amyloidosis
is discussed.

A 53-year old woman developed slowly progressive dysarthria, mild enlargement of the tongue and
dysphagia
since 1 year ago. All neurological differential diagnoses that could have explained the bulbar symptoms were excluded. The swallowing sequence was pathologic and immunoglobulins were markedly reduced. A bone marrow biopsy revealed light chain myeloma grade III. Amyloid deposits were found in the tongue but not in the kidneys. Oro-pharyngeal
amyloidosis
was held responsible for the described complaints. It is concluded that multiple myeloma must be considered in the differential diagnosis of bulbar paralysis and that biopsy of specific lesions is necessary to confirm local
amyloidosis
.

We report a 26 years old male with secondary
amyloidosis
and chronic renal failure who consulted due to a rapidly growing goiter associated with coarseness and
dysphagia
. Serum levels of thyroid hormones and TSH were normal and a neck CT scan showed a big mass in the anterior and lateral regions, that compressed neighboring structures. The patient was subjected to a total thyroidectomy and the pathological study revealed a diffuse fatty and amyloid infiltration of the thyroid gland. There was no evidence of malignancy.

Amyloidosis
is a rare disease in otorhinolaryngology. It presents a wide range of clinical manifestations and its deposits can be found in various organs. In the paper, a case of a 73-year-old female patient with macroglossia, as a symptom of nodular
amyloidosis
is reported. The predominant features were
dysphagia
and speech impairment caused by the tongue protruding beyond the teeth. The histologic appearance consisted of a nodular pattern of amyloid deposition. The amyloid was of an AL (lambda-light chain) type as shown immunohistochemically. The presented case shows the importance of investigating the patient for co-existing disease.

A 73-year-old woman who suffered from progressive hoarseness for 6 years and
dysphagia
without pain for 1 year presented with a soft tissue deposition on the posterior region of the vocal cords and narrowing in the subglottic area. Biopsy of this soft tissue and histological examination revealed laryngeal
amyloidosis
. A tracheostomy and partial removal of the amyloid were performed with general anesthesia. The airway was secured with a smaller diameter endotracheal tube, which was inserted atraumatically with Magill's forceps. The larynx is a rare site for
amyloidosis
. Laryngeal amyloidosis is fragile and hemorrhagic. Therefore, massive bleeding may occur during intubation. Anesthetists should take care in intubating the tracheas of these patients and be aware of other systemic diseases in laryngeal
amyloidosis
.
