1/84. adenolymphoma (Warthin's tumor) with multiple sarcoid-like granulomas.Five cases of adenolymphoma (Warthin's tumor) (AL) with numerous sarcoid-like granulomas within the lymphoid stroma are described. All patients were males, aged from 44 to 71 years (mean 57.3 years); all tumors were localized in the parotid gland. Fine needle aspiration cytology was performed in two cases 7.5 and 2 weeks before operation, respectively. Microscopic examination demonstrated the typical structure of AL. In addition, dispersed throughout the lymphoid stroma there were numerous granulomas formed by both epithelioid and multinucleated giant cells of Langhans type, strongly resembling sarcoidosis. The pathogenesis of the granulomatous change remains speculative. It could be caused by a toxic effect of the cysts' contents but probably not by its direct action; the spread of the fluid via sinuses into the lymphatic tissue seems to be more probable. We presume that the previous FNA may have some triggering effect. Granulomatous transformation of the lymphoid stroma resembling sarcoidosis is rare, but should be included in the spectrum of secondary changes in AL. It is not limited to metaplastic AL; it can be seen in an otherwise typical AL without any additional histologic changes. knowledge of a previous FNA and awareness of the possibility of this peculiar histologic change are necessary to avoid incorrect diagnosis.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
2/84. A case of sarcoidosis and sarcoid granuloma, papillary carcinoma, and Graves' disease in the thyroid gland.sarcoidosis is a systemic chronic granulomatous disease of unknown etiology most commonly affecting young females. The disease was first described in the thyroid gland in 1938. Our patient, a 27-year-old male with known sarcoidosis, was referred to the National University Hospital for acute symptoms of thyrotoxicosis (weight loss of 6 kg, tremor, thyroid enlargement, and tachycardia). Laboratory findings showed suppressed serum thyrotropin (TSH, <0.03 mU/L [0.5-4.20]), increased total thyroxine (T4) (223 nmol/L, [60-140]), and triiodothyronine (T3) (8.5 nmol/L, [1.5-2.7]). Furthermore, Tc-99m pertechnetate scintigraphy disclosed diffuse accumulation of the isotope confirming the diagnosis of Graves' disease. During the next 18 months of antithyroid treatment (thiamazole, Thycapzol) hyperthyroidism was difficult to control, the thyroid gland gradually enlarged, and surgery was recommended. Initially, the patient declined surgery but after an additional 18 months, he accepted surgery. During the 36-month period of antithyroid drug treatment TSH was suppressed (<0.01 mU/L) and T3 often elevated despite high doses of thiamazole. Total thyroidectomy was performed, and histologic examination of the removed thyroid tissue confirmed the diagnosis of Graves' disease and also the presence of sarcoid granuloma and metastatic papillary adenocarcinoma with spread to neck lymph nodes. Four months later, a modified radical neck dissection was performed with removal of neck lymph nodes followed by external radiation therapy (2 Gy x 32 fractions to the neck). The concomitant presence of sarcoidosis, papillary carcinoma, and Graves' disease in a thyroid gland, to our knowledge, has not previously been described in the literature.- - - - - - - - - - ranking = 7keywords = gland (Clic here for more details about this article) |
3/84. Severe xerostomia in a young man.We describe a previously healthy 24-year-old male waiter who presented with very severe xerostomia, such that he consumed an average of 7 pints of milk a day and seriously considered suicide. There were no other symptoms or signs of exocrine gland dysfunction. We discuss the differential diagnosis, investigation, and his subsequent complete response to therapy, with a review of the literature.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
4/84. Necrotizing sarcoid granulomatosis mimicking an intracranial neoplasm: clinicopathologic features and review of the literature.We present a unique case of biopsy-proven necrotizing sarcoidosis involving the central nervous system (CNS) in a 52-year-old woman. The patient presented with a 3-month history of left-sided headache and sharp, shooting pains on the left side of her face. She also has a previous history of sarcoidosis, histopathologically confirmed on parotid gland biopsy 24 years before. Imaging studies of the present lesion revealed a 1.8 x 1.4-cm mass in the left temporal lobe with signal intensity suggestive of meningioma or low-grade glial neoplasm. Surgical resection was initiated, and intraoperative consultation with frozen sections revealed granulomata. The lesion was biopsied, and surgical intervention was terminated. Permanent sections failed to reveal bacteria, mycobacteria, fungi, or foreign bodies. A diagnosis of necrotizing neurosarcoidosis was rendered. The patient was administered steroid therapy and clinically responded favorably. At the most recent follow-up almost 2 years later, there was no evidence of recurrence or progression. Necrotizing sarcoidosis has been reported most commonly in the lungs and rarely in other organ systems. We report the first histologically proven case involving the CNS as well as a rare example of sarcoidosis and necrotizing sarcoid granulomatosis in the same patient. sarcoidosis and its necrotizing variant should be considered in the differential diagnosis of a granulomatous mass lesion involving the CNS, particularly in the context of a history of systemic disease.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
5/84. Endoscopic diagnosis of sarcoidosis in a patient presenting with bilateral exophthalmos and pansinusitis.sarcoidosis is a chronic granulomatous disease of unknown etiology. Otolaryngologic and ophthalmologic manifestations occur in 15 to 55% of afflicted individuals, respectively. Neck masses, parotid enlargement, and facial nerve palsy are the most common presenting otolaryngologic complaints, while lacrimal gland enlargement, uveitis, and upper eyelid masses often call the attention of the ophthalmologist. biopsy reveals non-caseating granulomas, while the angiotensin converting enzyme (ACE) level may be elevated. We report an unusual case of a patient who presented with severe bilateral exophthalmos as the sole initial complaint. A prior workup included a negative conjunctival biopsy. On magnetic resonance imaging (MRI) and computed tomography (CT), the patient had pansinusitis. Endoscopic ethmoidectomies with tissue analysis revealed sarcoidosis. Further evaluation revealed no evidence of systemic disease, and all symptoms resolved with a course of oral steroids. Thus, nasal endoscopy and biopsy of affected paranasal sinus mucosa may prove a useful adjunct to the diagnosis of sarcoidosis, particularly in atypical cases.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
6/84. Lid swelling and diplopia as presenting features of orbital sarcoid.Sarcoid is an idiopathic multisystem non-caseating granulomatous disease with protean clinical manifestations. In the eye, the common sites of involvement are the skin of eyelid, conjunctiva, uveal tract, retina, optic nerve and lacrimal gland.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
7/84. Conjunctival biopsy in the diagnosis of ocular sarcoidosis.sarcoidosis is a multisystem granulomatous disease of unknown etiology that can affect almost every organ in the body, particularly the lungs, skin, eyes, and thoracic lymph nodes. A definitive diagnosis of sarcoidosis requires that a biopsy be performed. A specimen can be obtained from any affected ocular structure, including conjunctiva, lacrimal gland, eyelid skin, and orbit. Among them, conjunctival biopsy has been suggested as a sensible and safe procedure for confirming suspected sarcoidosis. We describe three patients in whom ocular symptoms were the sole initial manifestations of sarcoidosis and who were diagnosed based on the results of a conjunctival biopsy. We also discuss the efficacy of and indications for conjunctival biopsy.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
8/84. Sinonasal disease in patients with sarcoidosis.sarcoidosis is a chronic granulomatous disease of unclear etiology with a propensity to involve the lower respiratory tract, but may also involve the upper respiratory tract. Histologically, it is characterized by non-caseating granulomas of various organ systems. Although nasal and sinus involvement is uncommon, patients with sarcoidosis presenting with nasal and sinus complaints may have sinonasal sarcoidosis or simply rhinosinusitis. We reviewed the cases of six patients with pulmonary sarcoidosis who developed chronic sinonasal disease. All six patients had intranasal findings consistent with sinonasal sarcoidosis, but only four had histologic evidence of sinonasal sarcoidosis. These four patients continue to require extensive therapy including topical steroids, systemic steroids, intralesional steroid injections, and nasal irrigations. We conclude that patients with histologically proven sinonasal sarcoidosis present a significant therapeutic challenge because their symptoms and physical findings are often persistent despite aggressive medical and surgical therapy. Their recalcitrant sinonasal disease is thought to result from the destruction of cilia and mucus-producing glands by the granulomatous process.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
9/84. Mammary involvement in a patient with sarcoidosis.sarcoidosis is a systemic granulomatous disease of unknown etiology. sarcoidosis affects multiple organs; the lungs, lymphoid system, eyes and skin are usually involved. Commonly, any organ system may be affected. Sarcoid involvement in the nervous system, locomotor system, lacrimal and salivary glands, heart, kidney and liver has been recognized in patients with sarcoidosis. However, sarcoid involvement of the breast parenchyma has been extremely rare in patients with sarcoidosis. Herein, we report a patient with a sarcoid breast mass who had bilateral hilar lymphadenopathy and lymphocytosis in bronchoalveolar lavage analysis.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
10/84. sarcoidosis with giant parotomegaly.We report the case of a 63-year-old man with bilateral parotid gland sarcoidosis. Giant, elastic, hard, subcutaneous tumors had been present on the right parotic and submaxillary regions for 11 years and on the left for 1 year. The patient had had diabetes mellitus for 8 years. Noncaseating epithelioid cell granulomata were revealed histopathologically in the periductal area of the parotid gland. Bilateral hilar lymphadenopathy was noted on chest x-ray studies. serum levels of lysozyme were increased. Levels of serum angiotensin-converting enzyme were within normal limits. tuberculin skin reaction was positive. The tumors gradually improved after treatment with oral minocycline. Giant parotomegaly, as it occurred in this case, is very rare.- - - - - - - - - - ranking = 2keywords = gland (Clic here for more details about this article) |
