Tumors originating from ceruminous glands are rare lesions of the external auditory canal. The lack of specific clinical and radiological signs makes their diagnosis challenging. We report the case of an exceptionally rare benign tumor, a syringocystadenoma papilliferum (SCAP), in an atypical location in the bony segment of the external auditory canal with uncommon clinical signs. The special traits of the case included the following: the most lateral component of the tumor was macroscopically cystic and a granular myringitis with an obstructing keratin mass plug was observed behind the mass. The clinical, audiological, radiological, and histological characteristics of the neoplasm are consequently presented. Intraoperative diagnosis of the epidermal cyst was proposed. The final diagnosis of SCAP was determined only by histological analysis after the surgical excision. The educational aspects of the case are critically discussed.

Histopathologic Findings

Osteoma of the external auditory canal is a rare benign tumor with an estimated incidence of 0.05% of total otologic surgeries. In most cases, an osteoma in the external auditory canal does not cause symptoms because the tumor grows slowly and does not occlude the ear canal. However, if the mass grows to occlude the external auditory canal, several symptoms can occur, including conductive hearing loss, aural fullness, and keratin debris accumulation. We present two cases of this rare tumor in a 23-year-old woman and a 19-year-old man. The mass was surgically excised at the level of the peduncle under local anesthesia with microscope assistance. The base of the excised mass was drilled with a diamond burr to remove all osseous lesions. Histopathologic findings showed spongiotic osteomas. In these cases, patients had symptoms of aural fullness, although the osteomas did not completely occlude the external auditory canal, and the symptoms improved after surgical excision without recurrence.

Abstract Background: Desmoplastic fibroma (DF) is a rare, benign tumor. The most common sites are the long tubular bones and mandible. Although generally considered a benign tumor, it can invade surrounding tissues and has a high rate of local recurrence after incomplete surgical excision. However, there is currently no stantard treatment. Here we present a novel case of DF in the left 6th rib in a 35-year-old man.Case presentation: The man presented to our center with left chest pain and swelling. Enhanced computed tomography (CT) showed a 4.5×2.0 cm mass on the left 6th rib with pathological fracture.Wide resection was performed. Open biopsy revealed that the tumor destroyed medullary cavity and partially broke through the bone cortex. Pathologically, the tumor was composed of spindle-shaped cells arranging in a woven pattern on a backgroung of abundant collagenous fiber. No β-catenin were detected. Based on the pathological and radiological findings, a final diagnosis of DF was made. No postoperative adjuvant treatments were administerded. Fortunately, there was no evidence of recurrence 22 months after surgery. Conclusions: DF originated from rib is a kind of extremly rare benign tumor but locally aggressive and show unique biologically features. Wide resection or total resection can effectively reduce the risk of local recurrence when compared with curettage. Rarity of the tumor favors documentation in literature.

Ceruminous glands are specialized sudoriferous glands located in the external auditory canal (EAC). Tumors originating from these ceruminous glands are rare lesions of EAC; in particular, syringocystadenoma papilliferum (SCAP) is an extremely rare ceruminous glands neoplasm to occur in the EAC. Although it is rare, the association of SCAP with tubular apocrine adenoma in the background of nevus sebaceous on the body, extremities, and scalp is well documented. In this article, we report on a 60-year-old male who presented a mass in EAC, which was surgically removed. The final diagnosis of SCAP was determined by histological analysis and the patient has been well without recurrence.

AbstractPontocerebellar hypoplasia type 1B is a severe autosomal recessive neurologic disorder characterized by a combination of cerebellar and spinal motor neuron degeneration beginning at birth. Pontocerebellar hypoplasia type 1B is caused by mutations in EXOSC3 gene. High prevalence of the p.Gly31Ala mutation was found recently, especially in the Roma ethnic minority. We present a young Bulgarian Roma family with two deceased newborn children manifesting severe neuromuscular disorder including severe muscle weakness, respiratory distress, and multiple joint contractures. Based on the clinical signs and family's population characteristics, DNA testing for the previously described EXOSC3 in Bulgarian Roma mutation c.92G > C; p.Gly31Ala was performed on blood samples of both parents and they were found to be heterozygous carriers. This finding indirectly confirmed the diagnosis of pontocerebellar hypoplasia type B in the deceased offspring. Knowledge of population-specific molecular bases of genetic conditions was the key to final diagnosis in the presented family. Designing of population-based clinical-genetic panels may be a powerful diagnostic tool for patients with such origin. Preconception carrier screening in high-risk population groups is a feasible option to discuss.

Background. Osteoblastoma is a rare benign tumor. This tumor is characterized by osteoid and bone formation with the presence of numerous osteoblasts. The lesion is more frequently seen in long bones and rarely involves maxilla and mandible. Due to its clinical and histological similarity with other bone tumors such as osteoid osteoma and fibro-osseous lesions, osteoblastoma presents a diagnostic dilemma.Case Report. Very few cases of osteoblastomas involving maxillofacial region have been reported in the literature. This case report involves osteoblastoma involving right maxilla in an 18-year-old male patient. Following detailed clinical examination, radiological interpretation, and histopathological diagnosis, surgical excision was performed. The patient was followed up for a period of 3 years and was disease free.Summary and Conclusion. Benign osteoblastoma involving jaw bones is a rare tumor. There is a close resemblance of this tumor with other lesions such as fibro-osseous lesions and odontogenic tumors and thus faces a diagnostic challenge. Surgical excision with a long-term follow-up gives good prognosis to this lesion—Benign Osteoblastoma.

We have investigated prospectively the diagnostic accuracy, specialist satisfaction and patient–specialist rapport of a low-cost audio-visual link between a junior doctor with a patient and a consultant rheumatologist. Using a telephone link and subsequently a video-phone link, 20 patients, with various rheumatological problems, were presented by a junior doctor to the consultant rheumatologist for provisional diagnosis. All patients were then seen face to face by the consultant, when a final diagnosis was made. An independent consultant rheumatologist made a ‘gold standard’ diagnosis. Thirty-five per cent of diagnoses were made correctly over the telephone and 40% over the video-phone – there was no significant difference in the diagnostic accuracy between these two methods of communication. Rapport over the video-phone was universally poor. Where it was important, clinical signs could not be visualized over the video-phone and in more than 85% of cases small joint swellings could not be seen clearly.

A 22 years old male presented with a mass over the penis since birth, which was painless and gradually increasing in size. The mass was excised and it was found to be penile epidermal cyst. Epidermal cyst is one of the most common benign tumors occurring in the body, which commonly occurs either congenitally or following trauma or surgery, where the epidermal elements get trapped within closed space. But here this case had no trauma and surgeries in the past and the mass present since birth-a case of congenital penile epidermal cyst.
