DSM-5 Assessments of the Level of Personality Functioning: Intrapersonal and Interpersonal Functioning

Objective: In DSM-5, Section III, the Level of Personality Functioning (LPF) was proposed as a severity index of personality disorders (PDs), but as it reflects both trait-like (availability) and state-like (accessibility) features, of which, moreover, the relationship with the experience of patients is unclear, we critically examined LPF in patients with general psychopathology. Method: This study compared the validity of the direct Inventory of Personality Organization (IPO), and the indirect Differentiation-Relatedness Scale (DRS) LPF-measure, in relation to measures of intrapersonal and interpersonal functioning. The sample consisted of 70 inpatients with general psychopathology and no primary PDs. Associations of both measures with DSM-PDs were examined, with and without controlling for clinical distress. Results: The IPO was significantly related to age and clinical distress. When controlling for clinical distress, the IPO was still associated with cluster A (odd) and B (erratic) PD features, high levels of self-criticism, conflict in relationships and low levels of adaptive coping strategies. The DRS was only related to the schizotypical PD. Conclusions: In patients with general psychopathology, both the IPO and the DRS, appear to have limitations in measuring LPF. The IPO seems to be prone to state effects, although correlations with PDs remained significant when controlling for clinical distress. The DRS seemed to be more independent from clinical distress but was unexpectedly unrelated to features of personality pathology. DRS reflects availability, while IPO also reflects different degrees of accessibility of LPF in PDs.     

Cytopathological and immunocytochemical findings of pancreatic anaplastic carcinoma with ZEB1 expression by means of touch imprint cytology

Pancreatic anaplastic carcinoma (PAC) is rare and has an aggressive clinical course. We report an autopsy case of PAC focusing on the cytopathological characteristics of the tumor and immunocytochemical staining for vimentin, E‐cadherin, and zinc finger E‐box binding homeobox 1 (ZEB1), which markers are associated with epithelial markers of epithelial‐mesenchymal transition (EMT). A 50‐year‐old woman presented to our hospital with a chief complaint of jaundice. A pancreatic head tumor and multiple liver nodules were detected on abdominal computed tomography. Biliary cytology under endoscopic retrograde cholangiopancreatography suggested ductal adenocarcinoma. Three months after admission, she died of multiorgan failure. At autopsy, touch imprint cytology using squash preparation of the pancreatic tumor identified two different cell types; numerous isolated malignant cells with large and pleomorphic nuclei and a few clusters showing irregularly overlapped nuclei and irregular contours within the necrotic background. Immunocytochemically, isolated cells were positive for vimentin and ZEB1, and negative for E‐cadherin. Conversely, clusters were negative for vimentin and ZEB1, and positive for E‐cadherin. Histologically, the tumor was composed of sarcomatous cells with small foci of adenocarcinoma, which were consistent with a diagnosis of PAC. Immunohistochemical staining of the adenocarcinoma and sarcomatous cells corresponded to those of the clusters and isolated malignant cells, respectively. Immunostaining of these EMT markers is useful to distinguish sarcomatous cells from adenocarcinoma and can contribute to the accurate diagnosis of pancreatic tumors with EMT.     

Cytological findings of ROS1‐rearranged lung adenocarcinoma

ROS1‐rearranged lung adenocarcinoma has been recently identified. We report a case of ROS1‐rearranged lung adenocarcinoma with special emphasis on cytological findings. Here, we report a case of young woman with ROS1‐rearranged lung adenocarcinoma diagnosed by cytology and discuss the clinical, cytological, and molecular findings. Cytologically, the tumor consisted of small tight clusters of cells with high nuclear/cytoplasmic ratio. Nuclei were enlarged and small nucleoli were occasionally observed. Signet‐ring cells were focally identified. Neoplastic cells were positive for ROS1 immunocytochemistry. Subsequently, the translocation of ROS1 gene was confirmed in a histological specimen. In conclusion, the specific histology of adenocarcinoma on cytological materials should promote testing for ROS1 immunohistochemistry. Immunocytochemical detection of ROS1 protein helps identify patients suitable for molecular targeted therapy.
