Parasitic dermoid cysts may form from autoamputation of the ovarian mass secondary to torsion or rupture. It may then reimplant in surrounding structures and undergo subsequent neovascularization and further growth. The true incidence of these cases is unknown, however, a study reported a 0.04% incidence among 1,007 cases of dermoid cysts. This report describes the case of a 30-year-old multigravida who presented with an ultrasound finding of an ovarian dermoid cyst, which, upon laparoscopic surgery, turned out to be a parasitic dermoid cyst adherent to the bladder, with grossly normal bilateral ovaries. Theories on the development of parasitic dermoid cyst are also presented.

Objective: To investigate the clinical features, diagnoses and treatments of head and neck occupying lesions in newborns. Methods: All newborns with head and neck occupying lesions admitted to Neonatel Intensive Care Unit of the First Affiliated Hospital of Zhengzhou University form January 2014 to November 2019 were included. There were 23 males and 17 females, admission age was from 2 d-28 d, and the clinical manifestations, examinations, treatments and outcomes were evaluated. Results: Among 40 newborns with head and neck occupying lesions, 22 cases were admitted with dyspnea, 15 cases with masses in oral cavity or head and neck, 2 cases with fever as the first symptom, and 1 case with hoarseness as the first symptom. There were 5 cases with local infection. All cases were examined with local ultrasound and CT or MRI. Nine cases with severe dyspnea were treated with invasive ventilationm, of them 6 cases underwent invasive ventilation for more than 48 hours, 4 cases received tracheal intubation and artificial nose. Diagnostic punctures were performed in 2 cases. Seven cases received conservative treatments. Surgeries were performed in 31 cases, and 25 cases obtained pathologic diagnoses, including 3 cases of soft palate mature teratomas, 1 case of hard palate teratoma, 1 case of granulosa cell tumor, 1 case of lobulated spindle cell tumor in tongue base, 1 case of polyp in right glottis, 1 case of polyp at esophageal entrance, 4 cases of lingual root cysts, 1 case of laryngeal cyst, 2 cases of thyroglossal duct cysts, 2 cases of lymphangiomas, 1 case of lymphangioma with hibernoma, 1 case of tracheal cyst, 1 case of esophageal cyst, 3 cases of left neck abscesses, 1 case of occipital hemangioma, and 1 case of left temporoparietal abscess. Conclusions: The head and neck occupying lesions in the newborn is prone to upper airway obstruction. Imaging examination can assist the diagnosis. Different treatments can be selected according to the natures of occupying lesions.

Frontotemporal dermoid cysts with a cutaneous sinus tract in the sphenoid bone are rarely found, and furthermore, the spreading of these cysts across the frontal branch of the facial nerve has not been reported. Herein, we present a 5-year-old case of a dermoid cyst successfully resected with preservation of this nerve using a combined extracranial and intracranial approach. This approach is recommended for a safe and radical resection of the lesion and for securing an aesthetic outcome.

BACKGROUND: Dermoid cysts are congenital tumors that are benign. Dermoid cysts with intracranial extension can cause serious neurological complications. It is important, therefore, to determine whether a patient has a dermoid cyst when their chief concern at a doctor’s visit is a mass in the head or neck area. In this study, we present a literature review of dermoid cysts and an analysis of the authors’ experiences, with the goal of providing guidance useful for the diagnosis and treatment of dermoid cysts. METHODS: This study retrospectively analyzed the medical records of 62 patients who visited the two medical clinics with which the authors are affiliated. The patients were enrolled between October 2003 and January 2017. RESULTS: Of the 62 patients analyzed in this study, 32 were 0 to 5 years of age (52%) and 23 were 17 years of age or older (37%). Forty-seven patients underwent 1 or more imaging study during the process of diagnosis. Thirty-two patients were suspected to have a dermoid cyst. Forty-nine patients were analyzed to determine the depth of the cyst. Bone was seen in 43 patients through imaging tests or during actual surgery, and nine of the 43 had bony problems (21%). CONCLUSIONS: This study found that dermoid cysts were present in many adults, and that a high rate of deep lesions was observed, as well as many cases in which even the bone was affected. These results suggest, therefore, that dermoid cysts should be considered, and medical professionals should actively conduct imaging studies.

Dermoid cysts or mature cystic teratoma are the most common type of ovarian germ cell tumor. It may be complicated by torsion, rupture, chemical peritonitis and malignant change but is rarely complicated by infection. We present a case of an ovarian dermoid cyst with super-infection caused by Schistosoma haematobium (S. haematobium). We present here a case of incidental finding of S. haematobium eggs in an infected cystic teratoma of the ovary because of the rare occurrence of this lesion. A 45-year-old Moroccan woman admitted to the gynecological department because of abdominal pain and fever. Gynecological examination, ultrasonography, and abdominopelvic computed tomography scan revealed an ovarian mass thought to be a dermoid cyst. The pathological evaluation suggested infected ovarian dermoid cyst with the presence of adult worm in the tumor, contains same eggs of S. haematobium. Super-infection of an ovarian dermoid cyst is a rare event, and the association with S. haematobium is extremely rare in the literature.

PURPOSE: We report our experience with a case of orbital lymph node which has not been previously reported in the Republic of Korea. CASE SUMMARY: A 24-year-old female patient with no underlying disease visited our hospital with a 2-month history of a mass at the lateral side of the left upper eyelid. On physical examination, a round, well-defined subcutaneous mass was palpable, and pain, swelling or a skin change were not reported or seen. The appearance, location, and imaging findings of the mass were suspected to be dermoid, and excisional biopsy was performed for accurate diagnosis and treatment. The 1.0 × 0.7 cm-sized, round-shaped and brown-colored mass was excised. The mass was well-defined but in the posterior part; it was attached to the periosteum. The mass was finally diagnosed as a lymph node with lymphadenitis by histopathological examination. No recurrence or new lesion was observed after surgery, and the patient did not complain of abnormal symptoms. CONCLUSIONS: A Complete orbital lymphoid tissue has not yet been found in the orbit, and lymph nodes are known to be absent. However, as in this case, when an orbital mass is observed, the possibility of lymph node should be considered and histopathological examination should be performed to confirm it.

PURPOSE: The purpose of this study was to identify ultrasonographic features that can be used to differentiate between thyroglossal duct cysts (TGDCs) and dermoid cysts (DCs). METHODS: We searched surgical pathology reports completed between January 2004 and October 2015 and identified 66 patients with TGDCs or DCs who had undergone preoperative ultrasonography. The ultrasound images were reviewed by two radiologists who were blinded to the pathological diagnosis. They evaluated the following parameters: dimensions, shape, margin, location in relation to the midline, level in relation to the hyoid bone, attachment to the hyoid bone, the depth of the lesion in relation to the strap muscles, internal echogenicity, internal echogenic dots, multilocularity, the presence of a longitudinal extension into the tongue base, posterior acoustic enhancement, the presence of internal septae, and intralesional vascularity. RESULTS: There were 50 TGDCs and 16 DCs. TGDCs were significantly more likely than DCs to have an irregular shape, an ill-defined margin, attachment to the hyoid bone, an intramuscular location, heterogeneous internal echogenicity, multilocularity, and longitudinal extension into the tongue base. CONCLUSION: Ultrasound findings may inform the differential diagnosis between TGDCs and DCs.
