A rare case of huge congenital parieto-occipital teratoma in a female infant: An unusual site of occurrence

Teratomas are considered the most common congenital tumors located on the dorsal midline and arise from cells derived from more than one germ layer (i.e. ectodermic, endodermis and mesodermic) at different regions of the body. Those in the head and neck regions are considered rare with an incidence of 1-3.5% of all cases. Imaging provides critical information that helps in formulating differential diagnosis even though, history and physical examination provides critical information in making the diagnosis. A successfully surgically treated case of an usually huge parietooccipital teratoma in a 40 days old girl was presented with emphasis on the importance of imaging in diagnosis and management.

Malignant Lesions

Introduction. Palatine tonsils are part of the mucosa-associated lymphoid tissue, located in the oropharyngeal region. Although these tissues protect the body from foreign intruders, they are more prone to infections due to their anatomical structure and location. For instance, the differential diagnosis of a white lesion on the palatine tonsil can range from benign to malignant lesions. Oral lymphoepithelial cysts commonly arise as painless, yellowish nodules on the floor of the mouth and the ventral or lateral surface of the tongue. Case Presentation. This paper presents a rare case of an unusual site of a lymphoepithelial cyst (LEC) in the oral cavity. The lesion was located in the tonsil of a 20-year-old woman with a chief complaint of a painless, white lump in the back of the mouth for nine months. Discussion. The differential diagnosis of a white lesion on the palatine tonsil is caused by several factors, such as bacterial, viral, and fungal infections; trauma; stones; cysts; abscess; or cancer. In this case, both the clinical presentation and extra- and intraoral examinations were highly associated with LEC. Oral LEC etiopathogenesis is uncertain, and several theories have been proposed to discuss the causes of LEC. In addition, oral LEC could be monitored without surgical intervention if the nodule is asymptomatic. Conclusion. We emphasize the importance of a thorough clinical examination of oral and oropharyngeal lesions, which are usually neglected.

Ulcerative Lesions

Brucellosis is a disease that is transmitted from animals to humans mainly via the consumption of unpasteurized dairy products, and it can involve any organ all over the body. Here, we report a significant rare case of brucellosis with cutaneous manifestations in a 52-year-old male patient whose disease was diagnosed via a serology test. The patient received standard antibiotic treatment, and his cutaneous lesions healed quickly. Although the cutaneous manifestations of brucellosis are exceedingly rare, in case of encountering ulcerative lesions and other cutaneous findings, particularly in endemic areas, infection with brucellosis should be kept in mind as an important differential diagnosis.

Mesenchymal Neoplasm

Background: Lipoma is a benign tumor composed of mature white adipocytes and it is the most common soft tissue mesenchymal neoplasm. It is well separated from the surrounding tissues by a thin fibrous capsule. Lipomas occur in any part of the body that has fat tissues. 13% of such tumors are seen in the head and neck region. Angiofibrolipoma is a variant of lipoma with a prominent vascular component: Angiofibrolipoma is a subtype of lipoma composed of fibrocytes, capillaries and mature adipocytes. These tumors occur in the forearm, followed by trunk and in the extremities of young individuals. Its occurrence is very rare in the head and neck region. They are benign tumors that cause symptoms depending on their size and location. It is important to bear in mind this clinical entity in the differential diagnosis of the swellings that arise in relation to the tendon sheath. Patient and method: A patient with a recurrent swelling in the right wrist region was taken up for surgery with a clinical diagnosis of a fibrous tumor. Result: Histopathological diagnosis revealed the tumor as a rare variant of lipoma. Conclusion: This report highlights the fact that angiofibrolipoma should be considered in the differential diagnosis of swellings in different regions of the body.

Background: Hydatid cyst is a zoonotic disease due to the infection with the larvae of Echinococcus granulosus. The liver and lungs (80%) are the main organs involved and rarely head and neck. Case Presentation: A 47-year-old Iranian man presented to our center complaining of sublingual inflammation for 8 months. Sonography revealed a cystic lesion of 4×5×6 cm within the tongue. CT-scan showed a well-defined and hypodense mass in the floor of the mouth. Cyst resection was performed with the probability of ranula. Pathology was suggestive of hydatid cyst. Further workups revealed liver involvement. Therefore, he was treated with albendazole for 2 months. Conclusion: The hydatid cyst in the head and neck is rare and the involvement of sublingual gland is extremely rare. However, in endemic areas, hydatid cyst should be considered in the differential diagnosis of head and neck masses.

Latar belakang: tuberkulosis pada saluran nafas atas sangat jarang dijumpai dan biasanya disertai dengan penyakit paru primer. Dengan kemajuan pengobatan tuberkulosis saat ini, infeksi mycobacterium pada tonsil dan nasofaring jarang dijumpai. Limfadenopati servikal merupakan simptom yang sering terjadi, dan seharusnya didiagnosis banding dengan suatu massa di kepala dan leher. Tujuan: untuk menambah pengetahuan dalam mendiagnosis dan menangani tuberkulosis tonsil dan nasofaring yang jarang dijumpai. Kasus: Seorang anak laki-laki 14 tahun dikonsulkan dengan masa dileher bilateral disertai disfagia, demam dan malaise selama satu bulan. Penatalaksanaan: Pasien awalnya kami diagnosis banding sebagai suatu massa di kepala leher. Setelah ditegakkan diagnosis sebagai tuberkulosistonsil dan nasofaring disertai limfadenopati servikal dan tuberkulosis milier, diberikan terapi dengan anti tuberkulosis dan diperoleh hasil yang baik. Kesimpulan: Tuberkulosis sebaiknya dimasukkan sebagai diagnosis banding suatu massa di kepala dan leher terutama jika gambaran klinis dan pencitraan yang dijumpai tidak khas, sementara itu biopsi dan gambaran mikrobiologi selalu harus dipertimbangkan. Kata kunci: tuberkulosis nasofaring, tonsil, millier, limfadenopati. ABSTRACTBackground: Tuberculosis (TB) of the upper aerodigestive tract is rare and is usually associated with primary pulmonary disease. With recent advances in medical treatment of tuberculosis, mycobacterial infection of the nasopharynx and tonsil becomes very rare. The most common presenting symptom is cervical lymphadenopathy, so TB should be considered in the differential diagnosis of soft tissue masses of the head and neck. Purpose: To remind Otolaryngologists about the diagnosis and management of nasopharyngeal and tonsillar tuberculosis, which become rare case nowadays. Case: A 14-year-old boy was consulted with bilateral neck masses, disphagia, fever and malaise for one month. Case Management: At first we made a differential diagnosis of soft tissue masses of the head and neck. After he was diagnosed as nasopharyngeal and tonsilar tuberculosis with cervical lymphadenopathy and millier tuberculosis, the patient was treated with anti tuberculosis medication and the result was good. Conclusion: TB should be considered in the differential diagnosis of soft tissue masses of the head and neck, particularly when the imaging findings and clinical presentation are atypical, at which point appropriate biopsies and microbiologic studies should be conducted.
