A mediastinal mass was aspirated by fluoroscope-guided fine needle aspiration biopsy in a 47 years old female patient. The first aspiration smears were not diagnostic, because of hemorrhagic background and cell paucity. On the second aspiration, the smears were composed of some clusters of benign epithelial cells in hemorrhagic background. Cells were arranged in mostly solid sheets and tended to form glandular lumina in part. Their nuclei were round and vesicular. Nucleoli were not prominent. These findings were suggestive of benign glandular tissue, which was finally confirmed as mediastinal thyroid gland by open thoracotomy specimen.

PURPOSE:Craniopharyngioma is one of the most common causes of organic growth hormone deficiency leading to pituitary hormonal insufficiency. However, some growth hormone(GH)-deficient children with craniopharyngioma may grow normally or even show accelerated growth. This study was designed to evaluate several factors associated with growth of patients with craniopharyngioma. METHODS:Forty children operated on for craniopharyngioma were evaluated for their pituitary function, serum insulin like growth factor-I(IGF-I), serum insulin like growth factor binding protein-3(IGFBP-3) and serum prolactin levels. We also observed their growth status and corresponding changes with or without GH treatment. RESULTS:Among 40 patients, one had normal pituitary hormonal status and one had isolated GHD(GH deficiency). The other patients showed multiple pituitary hormone deficiency including GH(98%), LH, FSH(75%), TSH(65%), ACTH(62%), and ADH(38%) deficiencies. Patients with GHD were categorized into 2 groups. Group 1 consisted of children who showed normal growth, thus had not received GH treatment(n=14) and Group 2, those who showed subnormal growth(n=25). Patients in Group 2 were subdivided into Group 2A, when the patients had not received GH treatment in spite of subnormal growth(n=9) and Group 2B, when GH treatment had been added later on(n=16). There were no differences in the age at diagnosis of GHD, initial height standard deviation score(Ht SDS), body mass index(BMI), peak GH concentration between Group 1 and Group 2. Height velocities in Group 1, 2A, and 2B were 8.1+/-.2 cm/yr, 2.4+/-.2 cm/yr, 2.7+/-.2 cm/yr during the first year of endocrinologic follow-up, 7.1+/-.8 cm/yr, 1.2+/-.1 cm/yr, 7.6+/-.7 cm/yr during the second year, 5.9+/-.0 cm/yr, 2.8+/-.9 cm/yr, 7.3+/-.7 cm/yr during the third year, respectively. BMI changes during the first year of endocrinologic follow-up and postoperative prolactin levels were not significantly different between Group 1 and Group 2A. Postoperative IGF-I and IGFBP-3 levels in Group 1 were significantly higher than those in Group 2A(P<0.05). Both IGFBP-3 and prolactin levels correlated significantly with height velocity in Group 1 and 2A(P=0.004 r=0.64 and P= 0.035 r=0.74 , respectively). CONCLUSION: In this study, growth in children with craniopharyngioma was likely to be associated with IGF-I, IGFBP-3 and prolactin levels. Further studies are needed to unravel other growth promoting factors related to GH independent growth.

PURPOSE: In vitro sonography of lymph nodes was performed to ascertain the differential point between benignancy and malignancy. MATERIALS AND METHODS: Ninty-one lymph nodes were obtained at gastric cancer surgery and pathologically proved as benignancy in 68 and malignancy in 23 cases. Sohographic and pathologic correlation of resected ninty one lymph nodes was done in terms of size, the ratio of longest diameter versus shortest diameter, central hyperechogenicity, and peripheral cortical echo. RESULTS: Sonographic findings of benign lymph node were small size, oval shape(85%), narrow central high echogenicity(44%), and symmetric cortical thickening(41%). Sonographic findings of malignant lymph node were large size, round contour(39%), loss of central high echogenicity(82%), and diffuse increase of cortical thickness(82%). CONCLUSION: The most reliable sonographic criterion for differentiation of benignancy from malignancy was size of a lymphnode.

Cutaneous chromomycosis is a slow growing verrucous skin infection caused by five species, identified as Philadophara verruscosa, Fonsecaea dermatitidis, Fonsecaea pedrosoi, Fonsecaea compactum, Cladosporium, carionii. We report a case of chromomycosis of the skin causing by Cladosporium genus, in view of its rarity and unique light microscopic and ultrastructural features. This 65-year-old female had suffered from eczematous and lichenified skin lesion for the last two years since she burned her dorsum of the left hand by boiling oil. The lesion was slowly progressed, and ended up to the brownish hardening of the skin covered with crusts. Skin punch biopsy was done. Histologically, the sections revealed typical features of chronic granulomatous inflammation along with the heavy infiltration of the lymphocytes, plasma cells and histiocytes. Pseudocarcinomatous downgrowth of the epidermis and microabscesses in the upper dermis were also found. Numerous thick walled fungal organisms were noted within the giant cells and freely in the dermis, which were positive ant PAS stain, and diastase resistant. Thick mucous capsule is not observed. The organisms showed very faint yellowish walls with a few buddings and a few short elongated hyphae were also noted. Ultrastructurally, the fungus wall was multilayered and inner organelles were sparse. There is no evidence of systemic involvement, especially brain.

An 18-year-old man had suffered from intense burning with redness and an increased temperature of both the lower legs, forearms and hands since the age of 5. Symptoms were exacerbated by exposure to heat or walking. The patient obtained temporary relief by immersing his feet and hands in cold water. We observed the increase of skin temperature in relation to pain by thermography. No specific abnormalities were noted in laboratory studies. Treatment with aspirin was ineffective. We report a rare case of primary erythermalgia with typical features.
