Histiocytosis X is a disease of histiocyte proliferation in response to some unknown etiology. Thyroid involvement is extremely rare in the literature. In this paper, we present an 18-year-old female with histiocytosis X with thyroid involvement. This patient had had a goiter with normal thyroid function since 12 years of age. A thyroidectomy was done under the suspicion of thyroid cancer. Pathology revealed histiocytosis X. Hypoparathyroidism and hypothyroidism were noted after the operation and were treated with thyroid hormone, vitamin D and calcium carbonate. This patient also had lesions on the left side of mandible, in the suprasellar region and possibly in the right mastoid. A curettage biopsy of her mandibular lesion was also compatible with histiocytosis X. She was proven to have hypothalamic and pituitary dysfunction including hypogonadism and hypoadrenalism. Her thyroid lesion did not recur after the thyroidectomy. The toothache that she had also experienced subsided after the curettage biopsy of the mandibular lesion. Hypothalamic and pituitary dysfunction were controlled by hormone replacement. Because her disease had been running a benign clinical course, no chemotherapy was given.

A 23-year-old woman was supposed to undergo thoracoscopic surgery for the 10th pneumothorax that accompanied histiocytosis X. The past history included Lylle's disease, asthma, myocarditis, drug-induced leucocytopenia and bronchitis obliterans. The preoperative arterial blood gas analysis under receiving O2 at rate of 2 l.min-1 via a nasal cannula revealed normal values. General anesthesia and intubation with a double-lumen endotracheal tube would have been preferable, but regional anesthesia was chosen because of her medical history and positive results of the skin tests for vecuronium, pancronium, diazepam and midazolam. During the first 10 min of thoracoscopic procedure, her respiration became rapid and shallow and she was restless and comatose. The operation was cancelled. Arterial blood gas analysis under receiving O2 at rate of 4 l.min-1 via a face mask revealed: pH 7.025, PaO2 113.8 mmHg, PaO2 244.8 mmHg, HCO3- 29.7 mEq.l-1, BE-5.6, and O2 saturation 99.1%. Manual artificial ventilation with a mask and bag was initiated. Her spontaneous respiration and consciousness recovered in next 30 min. The postoperative course was uneventful. Tachypnea, caused from anxiety, dyspnea and stimulation of irritant receptors in the airway, were considered to be responsible for the event. The duration of inspiration became shorter as tachypnea developed, that made the tidal volume to decrease and hypercapnea ensued.
