Reduplicative Paramnesia

SummaryOrganic delusions are common, but have received little systematic study. Review of the literature reveals that they occur most commonly in toxicmetabolic processes and in disorders affecting the limbic system and basal ganglia. A prospective study of 20 consecutive patients with organic delusions revealed four general types of false beliefs: simple persecutory delusions, complex persecutory delusions, grandiose delusions, and those associated with specific neurological defects (anosognosia, reduplicative paramnesia). Simple delusions responded best to treatment, and complex delusions were more resistent. Acting on delusional beliefs was not unusual, and treatment of the delusions was an important aspect of management of the patient.

Abstract Primary thymic mucinous adenocarcinoma is extremely rare; to our knowledge, only 2 cases have been reported to date. We describe a third case of primary mucinous adenocarcinoma of the thymus in a 41-year-old man who presented with an anterior mediastinal mass with subsequent metastasis to the lung. The initial diagnosis was of metastatic mucinous adenocarcinoma, but extensive clinical workup of the patient failed to reveal a primary tumor elsewhere in the body. The specific identification of mucinous adenocarcinoma as a primary thymic neoplasm can be difficult or impossible. Morphologic and immunophenotypic similarities to mucinous adenocarcinomas of the gastrointestinal tract can pose diagnostic challenges for surgical pathologists, especially in small biopsy specimens.

<b><i>Introduction:</i></b> Scalp biopsy is a standard method for the definitive diagnosis of alopecia. The hair count parameters of each scalp area remain unclear. This study aimed to determine hair count values at different scalp locations from histopathology and to establish reference values for each part of the scalp. <b><i>Methods:</i></b> We obtained biopsy specimens from the frontal, vertex, temporoparietal, and occipital areas of the scalps of normal deceased subjects. All specimens were evaluated for the number of follicular units, hair counts, hair types, and stages of the hair cycle. <b><i>Results:</i></b> In total, 240 specimens were collected from 60 cadavers. Across all scalp sites, the temporoparietal area showed the lowest mean hair count, number of follicular units, terminal and vellus hairs, and terminal-to-vellus hair ratio. The average anagen-to-telogen hair ratio was comparable across all scalp sites. This study did not observe a significant association of hair parameters with gender differences or increasing age in all scalp areas. <b><i>Conclusions:</i></b> The present study revealed the diversity of the hair index among different scalp areas and suggested that normal hair count values should be separately standardized on each scalp region. Our findings may provide useful reference values for the histopathological evaluation of hair disorders in Asians.

Multiple Cranial Nerve

Rhinocerebral mucormycosis, a highly lethal fungal infection of the head and neck, is commonly recognized by its classic appearance. Two cases of this newly recognized clinical syndrome with isolated unilateral peripheral cranial nerve V, VI, VII, IX, X, XI, and XII palsies and initial sparing of the eighth cranial nerve are presented. Examination revealed that each patient had ulceration of the nasopharynx and osteitis of the base of the skull. Nose, orbits, paranasal sinuses, and intracranial nervous systems were initially spared. The cause of this obscure cranial nerve paralysis was diagnosed from biopsy specimens of the nasopharyngeal tissues and the demonstration of nonseptate hyphae. Review of the literature did not indicate that this syndrome had previously been recognized. The name nasopharyngeal mucormycotic osteitis is suggested.

Nocardiosis is primarily an opportunistic infection affecting immunosuppressed individuals, in whom it most commonly presents as pulmonary infection and sometimes cerebral abscesses. Isolated abdominal or retroperitoneal nocardiosis is rare. Here, we report the second case, to our knowledge, of isolated abdominal nocardiosis due to Nocardia paucivorans and provide a comprehensive review of intra-abdominal nocardiosis. The acquisition of abdominal nocardiosis is believed to occur via hematogenous spreading after pulmonary or percutaneous inoculation or possibly via direct abdominal inoculation. Cases of Nocardia peritonitis have been reported in patients on peritoneal dialysis. Accurate diagnosis of abdominal nocardiosis requires histological and/or microbiological examination of appropriate, radiologically or surgically obtained biopsy specimens. Malignancy may initially be suspected when the patient presents with an abdominal mass. Successful therapy usually includes either percutaneous or surgical abscess drainage plus prolonged combination antimicrobial therapy.
