We report herein on a case of minocycline-induced black thyroid with papillary thyroid carcinoma. A 60-year-old female, who had taken oral minocycline intermittently for osteomyelitis of the mandible for two years, noticed a palpable thyroid nodule. Fine needle aspiration of the nodule revealed atypical cells and the serum thyroglobulin level was high. Under the diagnosis of suspected thyroid carcinoma, a hemithyroidectomy with central compartment neck dissection was performed. The color of the tumor, which was diagnosed as a papillary carcinoma, was white. On the other hand, the color of the normal thyroid gland was dark red to black with minocycline pigmentation. Minocycline therapy may induce headache, nausea, vomiting, liver dysfunction and dental hyperpigmentation in children. But a minocycline-induced black thyroid is uncommon. Recently, there have been some reports that the risk of malignancy in black thyroid glands is higher than in non-black thyroids.

Congenital piriform sinus fistula, which is usually unilateral, is recognized as a cause of acute suppurative thyroiditis. We have encountered a rare case of bilateral piriform sinus fistulae. The patient, a 53-year-old female, was referred to our hospital because of right neck swelling, which improved after conservative treat. Three months later, an abscess of the left thyroid lobe was presented and was improved after incision and drainage. The diagnosis of bilateral piriform sinus fistulae was made by hypopharyngeal enhancement radiography. Total fistulectomies were performed. There was no recurrence observed six months after surgery.
