Chapter 65 discusses benign soft tissue masses, which are much more common than malignant lesions; however, there can be overlap between these categories, and some lesions have features that are indeterminate. In many cases, the clinical presentation is not clearly diagnostic, and patients with soft tissue lesions require additional evaluation with imaging and biopsy. Radiography, MRI, and US serve complementary roles in the workup of soft tissue masses, with MRI providing the most comprehensive evaluation in most cases. Although imaging sometimes cannot confirm a definitive diagnosis, the imaging appearance plays an important role in the workup of soft tissue masses and tumorlike conditions. The most important features to evaluate are the internal architecture of the lesion, defining the anatomic location of the lesion, and assessing the relationship of the soft tissue lesion to surrounding vital structures.

Abstract This four-part series of papers addresses the problem of systematic determination of the influence of several tire factors on tire treadwear. Both the main effect of each factor and some of their interactive effects are included. The program was also structured to evaluate the influence of some external-to-tire conditions on the relationship of tire factors to treadwear. Part I describes the experimental design used to evaluate the effects on treadwear of generic tire type, aspect ratio, tread pattern (groove or void level), type of pattern (straight rib or block), and tread compound. Construction procedures and precautions used to obtain a valid and functional test method are included. Two guiding principles to be used in the data analyses of Parts II and III are discussed. These are the fractional groove and void concept, to characterize tread pattern geometry, and a demonstration of the equivalence of wear rate for identical compounds on whole tread or multi-section tread tires.

Purpose: To evaluate the capability of color Doppler ultrasonography to differentiate between benign and malignant soft-tissue tumors. Material and Methods: We reviewed the ultrasonographic (US) and color Doppler (CD) findings in 46 consecutive patients with a palpable periskeletal mass. The presence of 3 or more vascular hila and of tortuous and irregular internal vessels within the lesions was considered an indication of malignancy. The CD diagnosis was compared with that obtained at US alone. Results: The sensitivity and specificity of CD were respectively 85% and 92%; these values were higher than those obtained at US alone, respectively 75% and 50%. Arteriovenous malformations presented as lesions with large internal vessels that had low vascular impedance and were easily diagnosed. The waveform patterns within solid tumors were not specific. Conclusion: At present, US is commonly employed to confirm the presence of a suspected soft-tissue mass, to locate it accurately, and to indicate its nature. CD findings enhance the role of the US technique in such lesions. The combined use of US and CD can allow the differentiation of benign from malignant lesions, and thus provide a better basis for treatment.

Undifferentiated mesenchymal (UM) cells, the progenitor cells of the cartilage layer, have been assigned a significant role in TMJ articular tissue maintenance. This was based on reports of UM cell reduction with increased soft-tissue thickness for the condyle and temporal component. However, the strength of this inverse relationship was not presented and remained unclear. The purpose of the present study was to assess the strength of the correlation between UM cell presence and soft-tissue thickness in young adult TMJs at autopsy. Sagittal histological sections from the central thirds of 50 joints were evaluated with respect to articular soft-tissue thickness, histological character, and UM cell presence in the condyle and temporal component. The superior sector ofthe condyle and the articular eminence showed the greatest variability in soft-tissue thickness and were the only areas to show localized UM cell absence. The eminence was the only location to show an inverse relationship between soft-tissue thickness and UM cell presence, and this was consistent in both an ANOVA (p = 0.0016) and a Spearman correlation analysis. However, the strength of this correlation was only moderate (rho = -0.52), and no such relationship was observed in any other location. This study suggests that the relationship between UM cell presence and soft-tissue thickness is more complex than previously hypothesized and that the contribution of UM cells to articular tissue maintenance has been overstated, while other biological processes were overlooked.

Purpose. To prospectively evaluate regional referrals into a soft tissue sarcoma service from outside the tertiary centre with local hospital imaging.Materials and Methods. Consecutive referrals were prospectively assessed for: patient demographics, source, referral date, date received by Multidisciplinary Team (MDT), lesion size, local radiology, MDT radiology and final diagnoses. Radiology diagnosis was categorised benign, indeterminate or malignant by consensus. Delays were defined as >10 days.Results. 112 patients were included with high correlation between local and MDT radiology categrorisation and histology (P=0.54andP=0.49, resp.). There was only a trend for MDT radiology diagnosis to downgrade local imaging diagnosis (n=15,P>0.05). 48 cases (43%) had ultrasound and MRI at referral and 20 (18%) ultrasound only. 85% of cases were benign (lipoma most common), 15% malignant (sarcoma most common). Delay occurred in 34% of cases.Discussion. In comparison to previous series these results show a reduction in benign lesions, increased biopsy and malignancy rate for lesions referred to a tertiary centre when imaging is performed and reviewed by local radiologists.Advances in Knowledge. Imaging triage of soft tissue masses can decrease benign referral rates and increase the proportion of indeterminate and malignant lesions referred to specialist centres.

Balanitis xerotica obliterans (BXO), first described by Stuhmer in 1928, is a chronic, progressive, atrophic, sclerosing process involving prepuce, glans and urethra. Its aetiology is unknown. After a short terminological excursus and a review of the aetiological hypothesis, we have focused on BXO in daily urological practice. We are here describing the clinical presentation and its differential diagnosis with premalignant and malignant lesions of the penis. We tried to define the relationship between BXO and squamous cell carcinoma of the penis. Particular attention was then cast on urethral stenosis. Finally, we focused on the treatment of BXO: corticosteroid local therapy as first line treatment or as adjuvant therapy after circumcision, surgical therapy including circumcision, laser therapy of the glans lesions, meatoplasty in the stenosis of the anterior urethra. We also stressed the need for histological examination of the preputial specimen for a correct follow-up and for medicolegal reasons.

Secondary Hemophagocytic Lymphohistiocytosis

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection may result in the multisystem inflammatory syndrome in children (MIS-C). The clinical presentation of MIS-C includes fever, severe illness, and the involvement of two or more organ systems, in combination with laboratory evidence of inflammation and laboratory or epidemiologic evidence of SARS-CoV-2 infection. Some features of MIS-C resemble Kawasaki Disease, toxic shock syndrome, and secondary hemophagocytic lymphohistiocytosis/macrophage activation syndrome. The relationship of MIS-C to SARS-CoV-2 infection suggests that the pathogenesis involves post-infectious immune dysregulation. Patients with MIS-C should ideally be managed in a pediatric intensive care environment since rapid clinical deterioration may occur. Specific immunomodulatory therapy depends on the clinical presentation. The relationship between the immune response to SARS-CoV-2 vaccines in development and MIS-C requires further study.

Isolation of Neisseria gonorrhoeae is currently the gold standard for the definitive diagnosis of gonorrhoea and for use in medico-legal cases in the UK. Molecular detection methods are used increasingly but are untested as evidence of infection in a court of law. An isolate of N. gonorrhoeae was obtained from a child and an article of clothing from an adult male who was suspected of sexual abuse of the child. Biochemical and immunological tests were used to confirm the isolate as N. gonorrhoeae. Amplification by PCR using two targets, cppB and ompIII, was used both as further confirmation of the isolate and to detect the presence of gonococcal-specific DNA from the clothing. The relationship of the gonococcal DNA from the child and the adult was investigated using genotyping (N. gonorrhoeae multi-antigen sequence typing; NG-MAST), including a nested PCR for the por gene. Both samples were indistinguishable by NG-MAST and shared the same sequence type, 403. This is the first report of molecular detection and genotyping of N. gonorrhoeae on an article of clothing, which resulted in conviction of the man for sexual assault.
