RESUMEN
The majority of neoplasms of the head and neck are of epithelial origin primarily including mucosal squamous cell neoplasms (papillomas; squamous cell carcinoma) as well as salivary gland neoplasms. However, the full spectrum of mesenchymal neoplasms (benign and malignant) typically arising in soft tissue sites may also develop in superficial layers of the upper aerodigestive tract. The diversity of mesenchymal neoplasms arising in the head and neck is beyond the scope of this article, and our focus will be on some of the more common and/or diagnostic problematic mesenchymal tumors occurring in the sinonasal tract, oral cavity/odontogenic, pharynx, larynx, and neck.

BACKGROUND: There is variation in the outcomes reported in clinical studies of basal cell carcinoma. This can prevent effective meta-analyses from answering important clinical questions. OBJECTIVE: To identify a recommended minimum set of core outcomes for basal cell carcinoma clinical trials. METHODS: Patient and professional Delphi process to cull a long list, culminating in a consensus meeting. To be provisionally accepted, outcomes needed to be deemed important (score, 7-9, with 9 being the maximum) by 70% of each stakeholder group. RESULTS: Two hundred thirty-five candidate outcomes identified via a systematic literature review and survey of key stakeholders were reduced to 74 that were rated by 100 health care professionals and patients in 2 Delphi rounds. Twenty-seven outcomes were provisionally accepted. The final core set of 5 agreed-upon outcomes after the consensus meeting included complete response; persistent or serious adverse events; recurrence-free survival; quality of life; and patient satisfaction, including cosmetic outcome. LIMITATIONS: English-speaking patients and professionals rated outcomes extracted from English language studies. CONCLUSION: A core outcome set for basal cell carcinoma has been developed. The use of relevant measures may improve the utility of clinical research and the quality of therapeutic guidance available to clinicians.

Primary liposarcoma of thymic stroma is an exceptionally rare tumor. Histological findings are often definitive for diagnosis, however due to the variability of nuclear atypia and the overlapping with other adipocytic tumors, ancillary techniques are helpful as confirmatory tools. Currently, Fluorescent in situ hybridization for MDM2 is the gold standard for diagnosis of well-differentiated and dedifferentiated liposarcomas, however a panel of immunohistochemical stainings, including MDM2, CDK4 and p16 is available as alternative method, helping to distinguish liposarcoma from its benign counterpart lipoma, especially in borderline cases. We describe the case of a young female diagnosed with a well-differentiated lipomatous tumor primary of thymic stroma with near cut-off result for MDM2-FISHand positive immunohistochemical staining for the panel described above. We discuss the challenges in the diagnosis of this rare entity andpresent an updated literature review.

BACKGROUND: Malignant tumor of the vulva is the fourth gynecological malignancy in frequency. Close to 70% of all vulvar malignancies are related to high-risk human papillomavirus (HPV) infection. METHODS: A search for non-HPV-related malignant tumors of the vulva was performed in the last 20 years (2000-2020) in the pathology database of a single tertiary institution. We aim to estimate the prevalence of non-HPV-related malignancies in our population, describe clinicopathological features of these tumors and investigate the expression of some potential therapeutic targets. RESULTS: A total of 71 patients were recovered; 26 patients (36%) had the diagnosis of extramammary Paget disease, 17 patients (24%) had basal cell carcinomas, 17 patients (24%) had primary melanomas, 10 patients (14%) had metastatic disease to the vulva and one patient (1%) had a primary dermatofibrosarcoma protuberans. Fifty-four percent of patients with extramammary Paget disease had a secondary malignancy and 12.5% had invasive disease. Programmed death-ligand 1 (PDL-1) was positive in seven out of nine primary melanomas and Her2/neu was overexpressed in six out of seven extramammary Paget disease. CONCLUSION: Non-HPV-related malignancies are important differential diagnoses in patient with vulvar lesions. Additional research is necessary to further understand these complex malignancies and potential new therapeutic targets.

BACKGROUND: Exome and targeted sequencing studies have identified potential driver mutations for a variety of tumor types. Cutaneous squamous cell carcinoma (cSCC) is one of the most highly mutated cancers but typically is associated with low rates of metastasis and high survival rates. Nevertheless, metastatic cSCC is a significant health threat; up to 8800 individuals die each year of this disease. METHODS: Because it is difficult to predict which cSCCs are more likely to metastasize, and because to the best of the authors' knowledge there are no targeted therapies specifically designated for patients with metastatic cSCC, exome and/or targeted sequencing of 18 metastatic and 10 primary cSCCs was performed to identify mutations that were more frequent in metastatic tumors and might be targeted for therapeutic benefit. The authors compared their results with published sequencing results of an additional 223 primary tumors and 68 metastatic cSCCs. RESULTS: The authors identified genes demonstrating higher mutation frequencies in metastatic cSCC compared with primary tumors, including the chromatin remodeling gene lysine methyltransferase 2D (KMT2D) and the classic skin tumor suppressor tumor protein p53 (TP53), which was found to be mutated in 54% of primary tumors compared with 85% of metastatic tumors (P<.0001). CONCLUSIONS: These studies appear to uncover potential pathways that are important in metastatic cSCC and that broaden understanding of the biology contributing to aggressive tumor behavior. These results may lead to new therapeutic strategies. Cancer 2017;123:1184-1193. © 2016 American Cancer Society.

BACKGROUND: Metastatic carcinoma of unknown primary origin to the head and neck lymph nodes (HNCUP) engenders unique diagnostic considerations. In many cases, the detection of a high-risk human papillomavirus (HR-HPV) unearths an occult oropharyngeal squamous cell carcinoma (SCC). In metastatic HR-HPV-independent carcinomas, other primary sites should be considered, including cutaneous malignancies that can mimic HR-HPV-associated SCC. In this context, ultraviolet (UV) signature mutations, defined as ≥ 60% CâT substitutions with ≥ 5% CCâTT substitutions at dipyrimidine sites, identified in tumors arising on sun exposed areas, are an attractive and underused tool in the setting of metastatic HNCUP. METHODS: A retrospective review of institutional records focused on cases of HR-HPV negative HNCUP was conducted. All cases were subjected to next generation sequencing analysis to assess UV signature mutations. RESULTS: We identified 14 HR-HPV negative metastatic HNCUP to either the cervical or parotid gland lymph nodes, of which, 11 (11/14, 79%) had UV signature mutations, including 4 (4/10, 40%) p16 positive cases. All UV signature mutation positive cases had at least one significant TP53 mutation and greater than 20 unique gene mutations. CONCLUSION: The management of metastatic cutaneous carcinomas significantly differs from other HNCUP especially metastatic HR-HPV-associated SCC; therefore, the observation of a high percentage of CâT with CC âTT substitutions should be routinely incorporated in next generation sequencing reports of HNCUP. UV mutational signatures testing is a robust diagnostic tool that can be utilized in daily clinical practice.

Background: Three-dimensional (3D) imaging using computer simulations is an evolving technology. There is a lack of strong data on the use of this technology for oncoplastic (OP) and reconstructive surgery. Methods: A prospective, randomized, single-center trial including breast cancer patients undergoing OP or mastectomy with immediate breast reconstruction with implant (IBR) enrolled from November 2019 to October 2021 at the Hospital Nossa Senhora das Graças, Breast Unit in Curitiba, Brazil. Both patients undergoing OP and those in the IBR group were randomized to undergo 3D imaging and simulation of postoperative results (intervention group) or 3D imaging without simulation (control group). All patients were invited to complete a patient-reported outcome (BREAST-Q) expectations module and breast reconstruction or reduction/mastopexy module before and 6 months after surgery. Results: A total of 96 patients were enrolled. Sixty-nine patients (45 OP and 24 IBR) completed the pre- and postoperative questionnaires and were randomized for the simulation. Women in the OP group had higher expectations for breast appearance when clothed than those in the IBR implant group (93.4 ± 16.3 versus 82.9 ± 26.5; P = 0.03). The intervention group was more satisfied with information than the control group (P = 0.021). Both patients who underwent OP and IBR believed that the 3D simulation helped them understand the surgical process (86.6% and 75%, respectively). Conclusions: Preoperative 3D simulation significantly improved patient's satisfaction with information and did not decrease postoperative satisfaction with the outcomes. The incorporation of preoperative 3D simulation may be a valuable tool in breast reconstruction.
RESUMEN
Multiple 3-tiered grading systems exist for mucoepidermoid carcinoma (MEC), leading to controversial results on the frequency and prognostic values of each grade. We aimed to identify prognostic histologic factors and to evaluate grading schemes in this retrospective study of 262 resected primary head and neck MECs. The rate of nodal metastasis was 8.4%. Large tumor size, tumor fibrosis, infiltrative border, lymphovascular invasion, perineural invasion, atypical mitosis, mitotic index (MI) ≥4/2 mm 2 (4/10 HPFs), necrosis, and pT4 stage were associated with increased risk of nodal metastasis. The 5-year recurrence-free survival (RFS) was 95%. Significant prognostic factors for RFS included infiltrative border, tumor-associated lymphoid stroma, architectural patterns (macrocystic, microcystic, and noncystic), anaplasia, atypical mitosis, MI, necrosis, lymphovascular invasion, margin, pT stage, and tumor size. Nuclear anaplasia, high mitotic rate, and ≥25% microcystic component were significant independent prognostic factors on multivariate survival analysis. There was no significant difference between low-grade (LG) and intermediate-grade (IG) MECs in terms of risk of nodal metastasis and outcomes using all 4 known grading systems. Rather, high-grade MEC was consistently associated with an increased risk of nodal metastasis at presentation and decreased RFS and distant metastasis-free survival (DMFS) compared with the LG/IG MECs. We therefore recommend simplifying MEC grading to a 2-tiered grading scheme using MI and/or tumor necrosis. Using a 2-tiered grading, high-grade histology independently predict RFS, and is associated with a 25% risk of nodal metastasis, a 5-year RFS of 76%, and a 5-year DMFS of 76%, whereas LG MEC has a nodal metastasis rate of 7.0%, 5-year RFS of 97% and 5-year DMFS of 99%.
RESUMEN
Background: IgG4-related disease is a rare, recently recognized chronic inflammatory disease. IgG4-related hypertrophic pachymeningitis (IgG4-RHP) of the central nervous system predominantly involves the cranial meninges. Spinal involvement remains rare. Objective: We report a case of recurrent cervicothoracic IgG4-RHP and review the surgical literature. Methods and Materials: A 35-year-old woman presented with a 6-month history of neck and right shoulder pain, progressive right triceps weakness and paresthesias in the right C8 and T1 dermatomes. MRI demonstrated a T2 hypointense epidural soft tissue mass extending from C6-T1. The patient underwent C6-T1 laminoforaminotomy and partial resection with near complete symptom resolution. Histopathology was consistent with diagnosis of IgG4-RHP. Eighteen months postoperatively, she experienced symptom recurrence necessitating re-operation and adjuvant postoperative prednisone with complete resolution at 40-months' follow-up. Results and Conclusions: Of the now nineteen confirmed cases of IgG4-RHP, fifteen underwent surgery. A majority achieved partial resection. Three surgical patients did not receive adjuvant therapy with symptomatic recurrence between 2 and 18 months.

Purpose: Benign endobronchial tumors are rare entities that can be difficult to diagnose because they often present with non-specific symptoms and vague radiographic findings. The current study reviews the clinical, radiologic and pathologic features, diagnosis, and treatment of patients with benign endobronchial tumors. Methods: We examined the charts of all patients who presented with biopsy-proven benign endobronchial tumors at a tertiary-care academic medical center between 1993 and 2018. Pertinent clinicopathologic and radiologic data were analyzed, with particular attention paid to treatment modalities and mean overall patient survival. Results: A total of 28 cases were identified. The most common benign neoplasm was hamartoma (37%), followed by lipoma (19%), squamous papilloma (11%), pleomorphic adenoma (7%), mucin gland adenoma (7%), papillary adenoma (3%), hemangioma (3%), neurofibroma (3%), leiomyoma (3%), and papillomatosis (3%). Cough (58%), shortness of breath (44%), and hemoptysis (15%) were the most frequent presentations. Most cases demonstrated well-defined submucosal or pedunculated endobronchial lesions with segmental pneumonia or atelectasis on imaging. Histologic diagnosis was obtained by endobronchial resection in 43% of patients, thoracoscopic lobectomy in 36%, endobronchial biopsy in 18%, and thoracoscopic wedge resections in 3%. All procedures were performed with no intraoperative or in-hospital deaths (mean overall survival: 20.2 years). Conclusion: Benign endobronchial tumors typically present as well-defined submucosal and/or pedunculated lesions, and may lead to post-obstructive complications. Endobronchial resection is the preferred strategy for diagnosis and treatment of these tumors.
RESUMEN
Cutaneous basal cell carcinoma is usually an indolent and slow-growing tumor with potential for local invasion and recurrence; however, metastatic events are exceedingly rare. The annual incidence of metastasis is estimated to range between 0.00281 and 0.05%. A retrospective search in the pathology database of a single tertiary institution was performed in the period between 1999 to 2019. Primary cutaneous metastatic basal cell carcinomas had paraffin blocks and glass slides retrieved. A total of 8673 cases was identified. The overall prevalence of metastatic tumors was 0.05% (4/8673). The median patient's age at diagnosis was 61 years old (range 52-79). The most common primary site of tumor was nose (2/4) and the most common histological subtype was infiltrative. The sampled lymph nodes were identified during primary tumor resection, except for 1 patient who had a sentinel lymph node biopsy performed as a surgeon individual decision. One patient had hematogenous spread to the pleura, diagnosed 5 years after diagnosis. In summary, this study adds new data to the current literature in metastatic primary cutaneous basal cell carcinomas and highlights the importance of early diagnosis and appropriate surgical excision in an effort to prevent local advanced disease, recurrence and lymphovascular dissemination.

BACKGROUND: The Paris system (TPS) for Reporting Urinary Cytology provides a standardized reporting system whose main focus is the diagnosis of high-grade urothelial carcinoma (HGUC). We conducted a study to see the impact of The Paris System on our cytologic diagnoses with associated histology. MATERIALS AND METHODS: We reviewed our pathology database regarding urinary specimens in the year before implementation of The Paris System and the year after. We gathered the data regarding cytologic diagnosis and concurrent/subsequent histology. RESULTS: Over a 1-year period from 2016-2017, 486 urine cytology specimens were identified before implementation of The Paris System and diagnosed as follows: 83% benign/negative, 10% atypical, 2% suspicious, 5% HGUC, 0.2% low grade urothelial neoplasm (LGUN), and 0.2% unsatisfactory. Over a next 1-year period from 2017 to 2018, 602 specimens used TPS and diagnosed as follows: 85% negative for HGUC, 6% atypical, 3% suspicious, 4% HGUC, 0.17% LGUN, and 2% unsatisfactory. Although, not listed as a standardized category in The Paris System, our institution used "Negative for high-grade, cannot rule out low-grade urothelial neoplasm (NHL)" as a subcategory of Negative for HGUC. 4% of the cases fell into this category. Focusing on the Atypical category before TPS, histology was available in 15/49 (31%) cases. Of these, 40% had HGUC. Regarding the Atypical category after TPS, histology was available in 21/36 (58%) cases. Of these, 52% were HGUC. For the NHL category, concurrent histology was available in 13/26 (50%) cases. Of these, 67% were low grade urothelial neoplasms. CONCLUSION: Our study showed that TPS lowered the rate of Atypical from 10% to 6%. After the implementation of TPS, Atypical corresponded to a higher rate of high-grade urothelial carcinoma. Also, the NHL subcategory had a high positive predictive value for diagnosing low grade urothelial neoplasms.

A lymphoid-rich stroma is a common finding in salivary gland tumors. Several reports documented this association with acinic cell carcinoma (ACC). However, cytologic studies reporting this phenomenon are rare and mainly confined to sporadic single case reports. We present the cytologic features of two cases of ACCs of the parotid gland displaying a lymphoid-rich background and discuss the cytologic differential diagnoses of this uncommon ACC variant.

Intrathyroidal parathyroid carcinoma is an uncommon malignancy. A 46-year-old male presented with a left neck mass. Computed tomography (CT) scan revealed a hypodense mass in the left thyroid lobe along with evidence of metastatic lymphadenopathy. Aspiration of the left thyroid nodule was performed, and a diagnosis of malignancy was rendered, favoring a primary anaplastic carcinoma. Based on the cytologic diagnosis, the patient underwent a total thyroidectomy. Before the surgery, intact parathyroid hormone (PTH) and calcium level (PTH = 78 pg/mL; Calcium = 10.6 mg/dL) were found to be minimally elevated. On gross examination, a 3.2 cm mass within the left inferior thyroid lobe was seen. Histopathologic examination and ancillary studies supported the diagnosis of a parathyroid carcinoma. We, hereby present, an exceedingly rare presentation of an intrathyroidal parathyroid carcinoma with only minimal elevation of PTH and calcium, mimicking a primary anaplastic thyroid carcinoma on cytologic examination.

Mycobacterial spindle cell pseudotumor (MSP) is a rare benign lesion characterized by a proliferation of bland spindle-shaped histiocytes with vague granulomatous formation, positive for acid-fast bacilli staining. This lesion is usually reported in the lymph nodes and skin of immunocompromised patients; only 6 cases primary in the lung have been reported in the English literature to this date. In this article, we present the case of a 42-year-old female status post failed kidney-pancreas transplant with subsequent multiple kidney transplants, on chronic immunosuppression, who developed a mass in the left lower lobe consistent with MSP. Mycobacterium xenopi was identified in lung tissue culture, an association never previously described in literature. This case report alerts for the possible association of this rare form of non-tuberculous mycobacteria in the pathogenesis of MSP and highlights the importance of this differential diagnosis in lung masses of immunocompromised patients.

Plasmablastic lymphoma (PBL) is an aggressive high-grade B cell lymphoma, considered a variant of diffuse large B cell lymphoma with approximately 75% mortality within 6-7 months. We describe an unusual case of PBL arising as a maxillary mass in an HIV-negative, nontransplanted 78-year-old female. Histologic examination revealed a diffuse infiltrate of anaplastic appearing cells exhibiting plasmablastic morphology with an adjacent contiguous infiltrate of mature appearing plasma cells. The PBL and mature plasma cell components both demonstrated an immunophenotype of CD20(-), CD38(+), and CD138(+). The two populations differed by the PBL featuring a high proliferation rate by Ki-67 (~95%) with coexpression of both c-MYC and EBV, while the mature plasma cell component featured a low proliferation rate by Ki-67 (~5%) without coexpression of c-MYC or EBV. Kappa/lambda staining demonstrated lambda light chain restriction involving the PBL, while the mature plasma cell infiltrate revealed kappa light chain restriction. Our findings describe the rare association of PBL with a synchronous distinct population of mature plasma cells exhibiting opposite light chain restriction.
RESUMEN
BACKGROUND: Fine-needle aspiration (FNA) of superficial and deep-seated lesions has been used with high sensitivity and specificity in the diagnosis of neoplastic and nonneoplastic lesions. However, literature of FNA in posttransplant patients is sparse, especially in postliver transplant. We undertook a retrospective study to evaluate the utility of FNA in the clinical management of post liver transplant patients. METHODS: We searched our institution's surgical/cytologic databases (November1993-February2016) to identify liver transplant cases and FNA procedures performed on allograft liver recipients. Institutional IRB approval was obtained for this study. RESULTS: 886 liver allograft recipients were reviewed, 41(5%) of which were transplanted for hepatocellular carcinoma. 62/886(7%) underwent an FNA procedure. 39males and 23females included with mean age of 58years. Mean time between transplant and FNA was 34months. 21/62(34%) were malignant neoplasms, most common malignancy was adenocarcinoma: 8cases(3lung,3pancreas,1colon,1cholangiocarcinoma)and 8cases of transplanted hepatocellular carcinoma patients had recurrence, 6 in the allograft liver and 1case each of metastasis to the iliac bone and periportal lymph node. 3cases were squamous-cell carcinoma (2lung and 1scalp). 2cases were posttransplant lymphoproliferative disorders. 34/62(55%) cases were benign aspirates from various organs (8lung,6liver,5pancreas,4breast,3thyroid,3lymph-nodes and 1case each of salivary gland, bile-duct,intraabdominal,abdominal wall,and oral cavity) 0.6/62(10%) cases were inflammatory. 22cases had histologic correlation: 5true-positives,16true-negatives,1false-negative (a patient with parotid mucoepidermoid carcinoma whose FNA diagnosis was sialadenitis), and no false-positive. The sensitivity was 83% and the specificity was 100%. The positive predictive value was 100% and the negative predictive value was 94%. CONCLUSIONS: This review shows that 40/62(65%) of the aspirates were benign lesions, indicating that a conservative approach is recommended in the clinical management of these patients, especially since the interval between transplant and FNA was on average 34months. FNA is a safe, minimally invasive method to follow-up these patients.

Importance: Patients undergoing skin surgery under local anesthesia can experience anxiety. Adjuvant intraoperative anxiety reduction methods may help. Objectives: To assess whether hand-holding or holding a stress ball reduces patient anxiety during excisional surgery of head or neck skin cancer with the patient under local anesthesia and to measure pain and patient satisfaction. Design, Setting, and Participants: In this nonblinded, single-center randomized clinical trial, performed from January 24 through April 26, 2017, at a dermatology outpatient service in an urban, academic medical center, a consecutive sample of 135 adults who required excisional removal of nonmelanoma skin cancer of the head or neck was randomized and studied. Interventions: Participants were randomized 1:1:1 to 3 groups: hand-holding, stress ball, or control (treatment as usual). Participants in the hand-holding group had a female researcher hold one of their hands during administration of anesthesia and extirpation, and those in the stress ball group held a round compressible ball and squeezed it as desired during the same period. Main Outcomes and Measures: The primary outcome was anxiety, measured by a visual analog scale (VAS), 6-item State Trait Anxiety Inventory (STAI), and physiologic measures (blood pressure and heart rate). Secondary outcomes were pain during the procedure and overall participant satisfaction. In addition, participants were asked how many hours they spent researching the procedure before surgery. Results: A total of 135 participants, 45 per study arm, were enrolled (mean [SD] age, 65.5 [13.9] years; 84 [62.2%] male; 134 [99.3%] white). There were no withdrawals or dropouts. Anxiety decreased over time in all groups, but no significant differences were found in the 3 anxiety measures across the 3 groups (VAS anxiety score before: control group, 3.11; hand-holding group, 3.04; stress ball group, 3.09 [P > .99]; VAS anxiety score during: control group, 1.89; hand-holding group, 2.31; stress ball group, 2.47 [P = .55]; STAI score: control group, 8.91; hand-holding group, 8.93; stress ball group, 8.76 [P = .96]). The 3 groups also did not significantly differ in postprocedure pain scores (control group, 0.78; hand-holding group, 0.64; stress ball group, 0.67; P = .85). Almost all participants (134 [99.2%]) were very satisfied. Participants who had done research had higher preoperative VAS anxiety scores (researched, 3.84; did not research, 2.62; P = .04). Conclusions and Relevance: Hand-holding and squeezing a stress ball do not appear to provide incremental anxiety reduction in patients during excisional skin cancer surgery. It is possible that some subgroups may respond better or that patients may respond better when able to select and tailor their preferred anxiety reduction method.
