Hibernomas are a very rare and benign soft tissue tumour that originate from brown adipose tissue. While they are not histologically malignant, they may be indistinguishable from aggressive tumours such as liposarcomas on imaging. It is, therefore, important to consider it as a differential diagnosis when a suspicious fatty lesion is seen on imaging. This may prevent unnecessary invasive surgery and patient stress. This paper illustrates the clinical presentation, radiological features, and histological diagnosis of a patient with a rare dumbbell-shaped hibernoma in the pelvis.

AbstractBackground:Solitary fibrous tumour is a soft tissue tumour of mesenchymal origin. It was first described in the pleura and has since been reported in many anatomical locations. Thirteen cases in the tongue have hitherto been reported. A positive CD34 result has traditionally been used to confirm the diagnosis, although this is often non-specific to solitary fibrous tumour. To date, nuclear STAT6 expression has not been reported in solitary fibrous tumour of the tongue.Method:This paper presents a further four cases of solitary fibrous tumour of the tongue, the largest series to date. Clinical, histopathological and immunohistochemical findings are detailed, including nuclear STAT6 expression.Results:All four cases were positive for CD34; two cases showed nuclear expression of STAT6. The tumours were excised completely and there have been no recurrences in at least one year.Conclusion:Solitary fibrous tumour should be considered as a differential diagnosis for tongue swellings, with the potential to recur.

Severe pain in the finger caused by an abnormal Pacinian corpuscle is a rare condition. We have recently encountered three patients diagnosed with a heterotopic Pacinian corpuscle, based on histopathological findings. When making a differential diagnosis of unexplained severe pain in the finger, abnormal Pacinian corpuscles must be taken into account in addition to glomus tumour and other types of painful soft-tissue tumour.

Primary rhabdoid tumors are highly malignant, rare tumors occurring in the renal, extrarenal soft tissue or central nervous system. They have non-specific radiological features and present with several histological components that create a problem in differential diagnosis with other embryonal tumors. We report a rare case of malignant rhabdoid tumor of the retina that presented with clinical features like those of retinoblastoma.

AbstractAngiomyoma is an uncommon, benign, soft tissue tumour characterised by bundles of smooth muscle cells intermixed with numerous vascular channels, which usually develops in the lower extremities. Oral manifestations are quite rare. Most oral cases occur in the lips and tongue; angiomyoma affecting the buccal vestibule is very rare. A case of angiomyoma in the buccal vestibule with a normal karyotype is reported.

A patient with a supraclavicular mass originally diagnosed as a lipoma who was referred to a plastic surgeon for definitive treatment is presented. Gross intraoperative findings were inconsistent with lipoma, and subsequent pathological evaluation revealed the mass to be a hibernoma (a benign, brown adipose tumour). The incidence, etiology, presentation, pathology and imaging characteristics of this somewhat rare soft tissue tumour are reviewed.

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. Keyword : Nasopharyngeal tuberculosis, tonsilar tuberculosis, cervical lymphadenopathy, milliertuberculosis

<p>A lipoma is a benign tumour that arises from an adipose tissue. It is the leading benign soft tissue tumour. It can occur anywhere in the human body. Lipomas in the gastrointestinal tract are quite rare and usually asymptomatic. We report a 70 years old male patient who presented with crampy abdominal pain. CT scan of the abdomen showed colo-colic intussusception. The patient was explored and the finding was colo-colic intussusception with a mass as a leading point. En-block resection done. Histology confirmed the mass as a lipoma.</p>
