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.

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.

Age And Sex

Histological analysis was performed on the liver of 27 cats of different breeds, age and sex, autopsied at the Department of Pathological Morphology of the Faculty of Veterinary Medicine of the University of Belgrade, and findings showed lymphoplasmocytic cholangiohepatitis, different degrees of fibrosis, passive hyperemia, fatty changes, cholestase, and neoplasms. The mentioned entities occurred very rarely as individual morphological manifestations, because the liver has different functions so that one morphological change often causes others to follow. Thus, for example, fibrosis was often followed by intrahepatic cholestase. Histopathological evaluation of liver disease is important not only in the autopsied samples, but also in diagnostics of liver diseases, in samples obtained by biopsy, which is important for making a precise diagnosis. The interpretation of the established histological changes in the liver requires close cooperation between clinicians and pathologists, because the final diagnosis is made on the grounds of morphological, biochemical and clinical findings.

Background: Amyloidosis refers to a group of systemic and localized disorders associated with the accumulation of misfolded protein aggregates called amyloids in different parts of the body. Owing to the existence of multiple forms of amyloids with similar tertiary structures, precise identification of their biochemical form is critical for correct therapy. Objective: This retrospective study aimed to determine whether typing of oral amyloid deposits can help diagnose a serious systemic condition in the early phase of the disease Methods: All histopathologically confirmed cases of amyloidosis managed over a 14-year period (January 1, 1997 to December 31, 2011) were retrieved for analysis. Two board-certified oral and maxillofacial pathologists reviewed the histopathological findings of amyloidosis on the basis of its classic Congo red staining characteristics. This was followed by immunohistochemical analysis of biopsy samples using a panel of antibodies specific for different forms of amyloidosis. Results: The most common location of amyloidosis was the tongue, and women were more commonly affected than men. The patient age ranged from 11 to 83 years (average 59.3 years). In patient 9, light-chain and pre-albumin (transthyretin) antibodies were related to arthritis and senile amyloidosis, respectively. The biopsy sample of patient 10, who was reported to have multiple myeloma, was positive for light chains and β2 microglobulin. All other samples exhibited localized (solitary) amyloidosis. Conclusion: Histological analysis coupled with immunostaining with a panel of specific antibodies might assist in identifying early systemic amyloidosis in patients with localized oral forms of the disease.

Congenital Syndrome

Epidermal nevus syndromes are a group of rare multiorgan disorders. Schimmelpenning syndrome is a clinical variant of epidermal nevus syndromes. This congenital syndrome is characterized by the existence of nevus sebaceous and usually accompanied by abnormalities of the eyes, skeletal, cardiovascular, and central nervous systems. A 2-year-old girl presented with large, hairless, yellowish-brown plaques on the scalp and face along with multiple brownish-black verrucose plaques and brownish-black macules on almost all parts of the body. The skin-colored verrucose tumors were also found on the lips and around the mouth. Histopathological examination of the lesion on the forehead revealed hyperkeratosis, acanthosis, and sebaceous gland hyperplasia supporting the diagnosis of nevus sebaceous, while histopathological examination of the lesions on the lips and abdomen demonstrated hyperkeratosis, acanthosis, and papillomatosis consistent with verrucous epidermal nevus. The pediatrician suspected that the patient had mental retardation; however, there were no neurological, cardiac, skeletal, nor ophthalmologic abnormalities. The lesions on the lips and around the mouth were excised, and it demonstrated a good result. To conclude, epidermal nevus syndrome (e.g., Schimmelpenning syndrome) should be considered in children born with nevus sebaceous.

Sensory Fibers

Background: Length-Dependent Sensorimotor Peripheral Neuropathy (LDSMPN) affects the longest nerve fibers in the body. Less well-appreciated, and absent from the current literature, is that LDSMPN affecting thoracic segments gives rise to ventral abdominal sensory loss on clinical exam. Methods: Consecutive patients seen for LDSMPN (n=30) were evaluated prospectively for the presence or absence of ventral abdominal sensory loss. Demographic variables, symptoms, quantitative neurologic findings (Neuropathy Impairment Score [NIS]) and final diagnosis were examined using descriptive statistics. Results: Ventral abdominal sensory loss was documented in 20/30 LDSMPN patients (66.7%), mean age was 64.1 years (range 33-81), M:F gender ratio was 19:11, mean NIS was 21.4 (range 0-77). NCS/EMG abnormalities were found in 25/30 patients, with 5/30 having a clinical exam and/or other electrophysiological evidence convincing for LDSMPN. LDSMPN patients without ventral abdominal sensory loss (n=10) had a mean age of 61.2 (range 45-73), M:F of 7:3, and mean NIS of 20.9 (range 0-54). Conclusions: 1) Ventral abdominal sensory loss appears to be common in patients diagnosed with LDSMPN of a variety of causes; 2) in addition to those innervating distal limb territories, distal sensory fibers from the thoracic region represent another category of length dependent involvement in LDSMPN; 3) the clinical examination of LDSMPN should include the ventral abdomen.

Diagnostic Investigations

An 11-year-old female British blue cat was referred for investigation of acute onset vomiting and marked abdominal enlargement. Diagnostic investigations confirmed a large volume of free gas within the abdomen and changes highly suspicious of an ulcerative gastric lesion. Exploratory surgery confirmed the presence of a perforated gastric ulcer and histological analysis showed only associated inflammatory change. The ulcerated lesions were resected, and the cat recovered rapidly with complete resolution of clinical signs. Spontaneous gastric rupture due complete perforation of an ulcer is rarely reported in cats. The vast majority of reported cases present with septic peritonitis, and the majority are subsequently diagnosed with neoplastic disease or a chronic inflammatory aetiology. The cat reported here had no evidence of septic peritonitis, and the authors feel a final diagnosis of idiopathic gastric ulceration is most likely.

Frequent Site

The ovary is a relatively frequent site of metastases from malignant neoplasia arising elsewhere in the body, the majority of these originating from the gastrointestinal tract. The best-known tumor of this type is signet ring cell adenocarcinoma (Krukenberg tumor) of gastric origin and large bowel. The gall bladder and bile ducts are extremely rare sources of these metastases. The casuistic describes a female patient, presented with pelvic mass and jaundice. While clinical and imaging results suggested a primary ovarian carcinoma with incidental cholelithiasis and choledocholithiasis, the final diagnosis was obtained on the basis of histopathologic findings of resected specimen.
