RESUMO

INTRODUCTION AND IMPORTANCE: Ameloblastoma is a benign but locally aggressive odontogenic tumor mostly occurring in the jaws. Ameloblastoma can be difficult to diagnose because it mimics other benign lesions. Its diagnosis requires a combination of imaging data, histopathological analysis, and molecular tests. Its treatment modality diverges from simple enucleation with bone curettage up to wide surgical resections. CASE PRESENTATION: A 25-year-old female presented with a right-sided mandibular mass for five years. Histopathology and radiology tests confirmed it to be an ameloblastoma. A hemimandibulectomy was done, followed by immediate reconstruction using an autogenously inserted iliac crest bone and a costochondral graft as an interposition graft for the lost part. The patient had a satisfactory clinical outcome, and no sign of recurrence after a follow-up of six months. CLINICAL DISCUSSION: The ideal management of ameloblastoma should minimize recurrence, restore function and appearance, and present minimal donor site morbidity. While the removal of a wide part of the bone and soft tissue leads to defects that may cause functional and aesthetic concerns, conservative management is associated with minimal downtime but high recurrence rates. Reconstructive surgery is of paramount importance for the recovery of the lost parts in these patients. CONCLUSION: Radical surgery is the treatment of choice for large tumors to minimize recurrence, and immediate reconstruction utilizing grafting techniques is essential to restoring function and appearance. The autologous bone graft technique is satisfactory for immediate mandibular reconstruction as it represents a simple, easy, less costly, and reliable method for restoring mandibular continuity defects.

RESUMO

CONTEXT.­: Breast pathology reports include many important details to guide clinical management. Reports with missing critical data elements are commonly seen in non-subspecialized pathology practices. The use of synoptic templates has been shown to improve pathology reports. Although synoptic templates are readily available by professional societies, many are not tailored to low-resource settings. OBJECTIVE.­: To perform an assessment of current breast pathology reporting at 3 referral hospitals in sub-Saharan Africa and design a locally adapted breast cancer synoptic template. DESIGN.­: We conducted semi-structured interviews with key stakeholders involved in breast cancer care including pathologists, radiologists, oncologists, and surgeons from Nigeria, Tanzania, and Mozambique. Moreover, each stakeholder reviewed a preliminary synoptic template that was compiled by using templates from the College of American Pathologists, Royal College of Pathologists, and International Collaboration on Cancer Reporting, and was asked to score each data element as essential, optional, or exclude. A locally adapted synoptic template was then designed from the needs assessment. Using the adapted templates, a retrospective review of breast cancer pathology reports from 2020 to 2022 was conducted to determine the completeness of reports at the 3 institutions. RESULTS.­: A total of 17 physicians were interviewed. Review of pathology reports revealed that none of the reports across all 3 sites contained all data elements considered essential by local physicians. CONCLUSIONS.­: There is an urgent need to improve breast pathology reporting in sub-Saharan Africa. Development and implementation of synoptic templates in collaboration with key stakeholders has the potential to improve pathology reporting practices in low-resource settings.

RESUMO

INTRODUCTION AND IMPORTANCE: Cystic hygroma is a benign congenital malformation of lymphatic and blood vessels, with an incidence of 1 in 6000 live births. Most cases are associated with genetic syndromes and can compromise fetal viability. Due to its rarity, comprehensive data is limited, mainly relying on case reports. CASE PRESENTATION: A 21-year-old pregnant woman at 27 weeks' gestation presented to triage with abdominal pain. Abdominal ultrasound revealed a single living female fetus with an estimated fetal weight of 734 g and a complex cystic mass causing hyper-extension of the neck. The pregnancy was terminated given the poor prognosis. Histopathology of the mass confirmed it to be a cystic hygroma. CLINICAL DISCUSSION: In limited-resource settings, management of huge cystic hygromas often necessitates termination of pregnancy due to a lack of sufficient resources for complex interdisciplinary interventions for the mother and infant after birth. In such cases, focus should be shifted toward promoting shared decision-making and sensitive patient counseling. CONCLUSION: Cystic hygromas that are diagnosed prenatally generally have a poorer prognosis than those diagnosed after birth. The management of cystic hygramas, particularly those diagnosed prenatally, represents a persistent challenge in low-resourced settings. Counseling and treatment recommendations must be tailored based on tumor characteristics, the expected prognosis, and the feasibility of medical or surgical intervention in a given clinical environment.

RESUMO

BACKGROUND: Concomitant invasive ovarian mucinous adenocarcinoma, unilateral renal agenesis and bicornuate uterus is a rare combination. Unilateral renal agenesis has been associated with genital anomalies, such as unicornuate and bicornuate uterus. Furthermore, a wealth of studies has reported the association between unicornuate uterus and ovarian anomalies, such as the absence of an ovary or ectopic ovaries, but rarely has there been a combination of the three to the best of our knowledge. The present case report is the first case presentation with a combination of the three syndromes: ovarian mucinous tumor, unilateral renal agenesis, and bicornuate uterus. CASE PRESENTATION: We report the case of a 17-year-old who presented with abdominal distension. On examination, a CT scan revealed a large multicystic abdominal mass on the right side, with an absence of the right kidney while the left kidney was normal in size, appearance, and position. Intraoperatively, massive blood-stained ascitic fluid was evacuated. Additionally, a large whitish polycystic intra-abdominal mass with mucus-like materials and solid areas was attached to the midpoint of the colon and the right ovary, with visible metastasis to the omentum. The uterus was bicornuate. The mass and omentum were taken for histopathology and a diagnosis of invasive ovarian mucinous cystadenocarcinoma with metastasis to the colon and omentum was made after a pathological report. CONCLUSIONS: The presence of these conditions in the same individual could potentially complicate medical management and fertility considerations. Thus, a need for a multidisciplinary medical team, including gynecologists, urologists, and oncologists, to address their unique needs and provide appropriate treatment and guidance. Further research and case studies are needed to better understand the possible association and implications of these rare co-occurring conditions.

RESUMO

BACKGROUND: Breast cancer is prevalent worldwide, with disparities in screening, diagnosis, treatment outcomes, and survival. In Africa, the majority of women are diagnosed at advanced stages, affecting treatment outcomes. Screening is one of the best strategies to reduce mortality rates caused by this cancer. Yet in a resource-constrained setting, there is limited access to screening and early detection services, which are available only at a few referral hospitals. OBJECTIVES: We aimed to evaluate the prevalence and screening results of breast cancer using clinical breast examination coupled with fine needle aspiration cytology in a resource-constraint setting. DESIGN: A combined cross-sectional and cohort study. METHODS: Women at risk of developing breast cancer in the Kilimanjaro region of Tanzania were invited, through public announcements, to their primary healthcare facilities. A questionnaire was used to assess the participants' characteristics. The women received a clinical breast examination, and detectable lesions were subjected to a confirmatory fine needle aspiration cytology or an excisional biopsy. Preliminary data from this ongoing breast cancer control program were extracted and analyzed for this study. RESULTS: A total of 3577 women were screened for breast cancer; their mean age was 47 ± 7.53 years. About a third of them (1145, 32%) were practicing self-breast examination at least once a month. Of 200 (5.6%) with abnormal clinical breast examination, 18 (9%) were confirmed to be breast cancer, making the prevalence to be 0.5%. The vast majority of participants with breast cancer (13, 72.2%) had early disease stages, and infiltrating ductal carcinoma, no special type, was the most common (15, 83.3%) histopathology subtype. Hormonal receptor status determination results indicated that 11 (61.1%), 7 (38.9%), and 5 (27.8%) of the tumors overexpressed estrogen receptor, progesterone receptor, and human epidermal receptor-2, respectively. CONCLUSION: Our study demonstrates 5.6% of Tanzanian women have abnormal clinical breast examination findings, with 9% having breast cancer. Nearly three-quarters (72.2%) of breast cancer screened for early disease were detected in the early disease stages. This finding suggests that organized screening with clinical breast examination coupled with fine needle aspiration cytology, which is a simple and cost-effective screening method, has the potential to improve early detection and outcomes for breast cancer patients in a resource-constraint setting.

RESUMO

Verrucous carcinoma is a well-recognized low-grade variant of squamous cell carcinoma. Cutaneous, oral, and anogenital forms exist. Exposure to persistent chronic irritation, inflammation, and repeated injury, as well as carcinogenic agents such as human papillomavirus infection, smoking, and alcohol use, are established risk factors. These neoplasms occur mostly in the oral cavity. The usual extraoral sites include the larynx, esophagus, genitals, and perineum. It is an extremely uncommon site of occurrence for the extraoral chin region. This unusual location makes the index case unique. Other uncommon sites reported include finger and foot. Case studies of verrucous carcinoma with huge tumor sizes are rare. Although it can be destructive locally, verrucous carcinoma typically does not spread to distant sites. Wide surgical excision with free margins is the most common treatment approach with a favorable prognosis. These tumors are likely to recur if they are incompletely excised, and recurred lesions tend to be more aggressive clinically as compared to their original counterparts. Herein, the authors describe a case of a huge oral verrucous carcinoma localized on the chin of a 43-year-old female patient. The clinical course, diagnostics, and proposed treatment have been discussed with the existing available literature.

RESUMO

Ossifying fibroma (OF) is a slow-growing benign fibro-osseous neoplasm. It is mostly odontogenic in origin, and it arises in the jaws, particularly the mandible. OF is characterized by the production of bone and cementum-like calcifications in a fibrous stroma. OF reports of the bone of the maxilla are uncommon. Diagnosing OF can be challenging due to the considerable overlap of clinico-pathological characteristics with those of other neoplasms. Herein, the authors describe a case report OF in a 26-year-old male who presented with a huge fibro-osseous tumor of the maxilla. Histopathology established the diagnosis of maxillary OF. The tumor was surgically removed via a Weber-erguson approach with satisfactory functional and cosmetic results. No recurrence has been found after one year of follow-up. Clinical, radiological, and pathological characteristics, as well as surgical treatment approaches, are further discussed. This is one of a few documented cases of maxillary OF in our setting.

RESUMO

BACKGROUND: Although prostate cancer (Pca) screening plays important role in early diagnosis and reduction of mortality, Tanzanian men are relatively unscreened. We aimed to investigate Pca knowledge level and barriers to screening among at-risk men in northern Tanzania. METHODS: This community-based survey was conducted in northern Tanzania from May to September 2022, involving men age ≥40 years. Participants were invited by announcing in local churches, mosques, brochures, and social media groups. Participants attended a nearby health facility where survey questionnaires were administered. Knowledge level was measured on the Likert scale and scored as poor (<50 %) or good (≥50 %). RESULTS: A total of 6205 men with a mean age of 60.23 ± 10.98 years were enrolled in the study. Of these, 586 (9.5 %) had ever been screened for Pca. Overall, 1263 men (20.4 %) had good knowledge of Pca. Having health insurance, knowing at least 1 risk factor or symptoms of Pca, and hospital as the source of Pca information were significantly associated with ever being screened. The most common reasons for not being screened were a belief that they are healthy (n = 2983; 53.1 %), that Pca is not a serious disease (n = 3908; 69.6 %), and that digital rectal examination (DRE) as an embarrassing (n = 3634; 64.7 %) or harmful (n = 3047; 54.3 %) procedure. CONCLUSION: Having Pca knowledge, health insurance and hospital source of information were correlated with increased screening. False beliefs about DRE and the seriousness of Pca had negative effects on screening. Increasing community knowledge and universal health coverage would improve uptake of Pca screening.

RESUMO

INTRODUCTION AND IMPORTANCE: Benign prostate hyperplasia is common condition among elderly men, but giant intravesical prostatic protrusion is rare and may be confused with bladder carcinoma. CASE PRESENTATION: We report an unusual case of giant intravesical prostatic protrusion mimicking bladder carcinoma. A diagnosis of giant intravesical prostatic protrusion was confirmed with the assistance of cystoscopy and patient was managed by transvesical simple open prostatectomy where he had uneventfully recovery. CLINICAL DISCUSSION: Both bladder carcinoma and benign prostate hyperplasia are more prevalent in elderly men and they all present with lower urinary tract symptoms. Ultrasound and computer tomography may all suggest bladder carcinoma. The two conditions are treated differently, and therefore having correct diagnosis is mandatory. Cystoscopy is an important investigation that can act as a tiebreaker in differentiating giant intravesical prostatic protrusion from bladder carcinoma. Transvesical simple open prostatectomy is the preferred surgical approach with good postoperative outcome. CONCLUSION: This case report reminds urology surgeons on the possibility of having giant intravesical prostate mimicking bladder carcinoma and the importance of cystoscopy in differentiating the two. Transvesical simple open prostatectomy has promising result.

RESUMO

Key Clinical Message: Rhabdomyosarcoma of the female genital tract often involves the vagina and cervix. It usually occurs in infants and children. Such tumors are uncommon in the uterus, especially in adults. Treatment options are based on studies of younger individuals. Abstract: Rhabdomyosarcoma (RMS) is a malignant mesenchymal neoplasm with a tendency to differentiate into skeletal muscle cells. RMS is an aggressive tumor that tends to develop in children and younger patients. A vast majority of genital tract RMSs occur in the vagina and cervix. Such tumors rarely occur in adults. Usually, these tumors either occur as a component of a biphasic uterine tumor (carcinosarcoma or adenosarcoma) or can be a pure heterologous tumor. Pure uterine RMSs are extremely rare in adult patients and difficult to diagnose. Accurate diagnosis of these tumors depends on precise histopathological evaluation. The present report describes a rare case of embryonal RMS of the uterus in a postmenopausal female and explores the most recent literature. The aim is to strengthen the existing literature and aid clinicians in the management of similar cases. A 64-year-old postmenopausal female presented with a history of abdominal pain associated with abdominal distension, per vaginal bleeding, and foul-smelling discharge for 6 months. A transabdominal ultrasound revealed a bulky uterus with a well-circumscribed heterogeneous lesion. Histopathology confirmed the diagnosis of high-grade embryonal RMS within the corpus region of the uterus. A total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed, followed by adjuvant chemotherapy to prevent relapse of the disease. Six months after oncological care has passed, the patient remains symptoms-free without evidence of recurrence or metastasis.

RESUMO

Key Clinical Message: The mainstays of treatment for granuloma pyogenicum include careful evaluation of any penile growth, thorough excision of the polypoid, histological examination, and close monitoring to check relapse and management. Abstract: Pyogenic granuloma is an acquired noncancerous vascular proliferation that arises from the mucosa and skin, seldom subcutaneously or intravascularly. It is also referred to as telangiectasis granuloma or lobular capillary haemangioma. The risk factors include vascular abnormalities, medicines, hormones, and microtrauma. We discussed the case of a 24-year-old man who had a poorly managed ventral distal penile polypoid lesion at a peripheral hospital. Upon further histopathological examination, the diagnosis of pyogenic granuloma was made. Histopathologically speaking, the term "pyogenic granuloma" is misleading because the illness is not linked to the production of granulomas. Pyogenic granuloma's etiopathogenesis is still unknown; true hemangioma is thought to be a reactive hyperproliferative of the vasculature brought on by a variety of stimuli; pyogenic granuloma may be caused by uneven angiogenic factor production in response to minor local trauma or cutaneous disease. Histopathological analysis and surgical excision are the methods used for diagnosis and treatment. The mainstay of treatment for granuloma pyogenic granuloma includes careful evaluation of any penile growth, thorough excision of the polypoid, histological examination, close follow-up to check for relapse, and early management.

RESUMO

Key Clinical Message: Gestational macromastia is a rare disorder involving excessive breast tissue enlargement during pregnancy, potentially threatening the fetus and the mother. Our patient's previous pregnancies were more physiological, without any associated symptoms. Abstract: Moderate bilateral enlargement of the breasts is a normal finding during pregnancy and lactation. Occasionally, there is a continuity from this physiological hypertrophy to massive breast hyperplasia or gigantomastia, causing complications that threaten the wellbeing of the fetus and the mother or raising alarm for a malignant disease. We present a case of a 28-year-old G3P2L2 with a gestational age of 29 weeks complaining of massive bilateral breast enlargement for 6 months, accompanied by a threatened abortion. The masses began gradually after conception and increased gradually over time. Notably, the breasts had been unremarkable in her two previous pregnancies. The breast ultrasonography and mammography findings pointed to a benign neoplasm. Histopathology of the lesions reported bilateral ductal hyperplasia. Conservative management and close follow-up were initiated. A cesarean section was performed due to cord prolapse, and a 1.3 kg male baby was extracted. Unfortunately, the neonate succumbed after 3 days due to apnea of prematurity. The patients' breast size subsided considerably with time. Unusually large tumors can cause alarm for other pathologies, such as breast cancer. The radiological tests should reassure the attending practitioner, and the histological examination should confirm the diagnosis. An understanding of the typical and atypical clinico-pathologic characteristics of breast lesions occurring in pregnancy and lactation is essential for appropriate patient care.

RESUMO

It is quite unusual to have numerous primary malignant tumors at the same time in the same patient. These cancers are classified as metachronous or synchronous. The occurrence of synchronous urologic tumors poses diagnostic and treatment challenges and has always been a subject of controversy in the clinical decision-making process. Unfortunately, no clear standardized management protocols for these patients exist. Therefore, diagnosis and treatment may be difficult, especially with few resources. We present a 75-year-old man with simultaneous prostate and kidney cancers successfully treated at our center. This is one of the rare cases in the English literature with two primary urologic cancers.

RESUMO

Liposarcoma is a tumor derived from primitive cells that undergo adipose differentiation. They comprise 10%-35% of all soft tissue sarcomas. We present a 46-year-old female patient with a 4-year history of a giant swelling on the lateral aspect of the left thigh. Wide local excision of the mass was performed and histopathological analysis revealed a well-differentiated liposarcoma. Liposarcomas commonly appear in the extremities and have distinct features on imaging studies. Surgical treatment and histology are the most important prognostic factors for patients with lipomatous tumors, as complete surgical excision reduces local recurrence rate.

RESUMO

Key Clinical Message: Ventricular myocardial rupture is a rare complication of myocardial infarction. It occurs within hours to weeks after an infarction. Mortality is high. Antemortem diagnosis is a challenge in low-resource settings, leading to potential misdiagnosis. Abstract: Left ventricular myocardial rupture is a potentially fatal yet common complication in acute myocardial infarction patients. Rupture can occur as early as hours after an infarction. However, rupture may also occur later in the first week in the setting of myocardial necrosis and neutrophilic infiltration. Patients may survive several days to weeks before rupture occurs, and cardiac tamponade may present subacutely with a slow or repetitive clinical course. Sudden death can be attributed to ventricular rupture, more commonly during this time frame. Myocardial rupture can also occur as a result of trauma, infections, or cancer. Mortality is exceedingly high if surgical intervention is delayed. In most patients, myocardial rupture manifests as a catastrophic event within days of a first, small, uncomplicated acute myocardial infarction. Acute onset of shortness of breath, chest pain, shock, diaphoresis, unexplained emesis, cool and clammy skin, and syncope may herald the onset of ventricular septal rupture after acute myocardial infarction. Sudden death from myocardial rupture during acute myocardial infarction in patients with no apparent previous symptoms of myocardial ischemia represents a challenge for medical examiners, law enforcement officers, and society as a whole. An autopsy is critical for establishing the cause of death. We present the case of a 54-year-old male whose body was found beside the road after a trivial quarrel a day before. Further medical information about the deceased was not available. The preliminary cause of death was presumed to be traumatic. No evidence of trauma was seen during the autopsy. Massive pericardial blood collection compressing the heart and concealed left ventricular myocardial rupture were noted. Histopathological examination of the heart demonstrated myocardial infarction with a tear associated with bleeding that was contained in the pericardial sac. We ruled cardiac tamponade as the cause of death due to an infarcted myocardial rupture. Antemortem diagnosis of myocardial rupture can be challenging in low-resource settings, leading to potential misdiagnosis and negative impacts such as community conflicts.

RESUMO

Intussusception is rarely seen in adulthood but is commonly seen in the pediatric age group. Causes of intussusception in adults are commonly due to tumors and inflammatory diseases. Intussusception in adults accounts for less than 5% of intestinal obstruction. Colonic lipomas are usually asymptomatic and are mostly managed surgically with promising outcomes as seen in our case.

RESUMO

Key Clinical Message: A rare form of invasive breast carcinoma, NOS, also known as matrix-producing carcinoma made up of epithelial and mesenchymal components. Usually, they are triple negative and clinically aggressive and respond poorly to neoadjuvant systemic therapy. Abstract: Metaplastic breast carcinomas (MBCs) are ductal carcinomas that undergo metaplasia to form nonglandular growth patterns. They are extremely rare, constituting less than 1% of all invasive breast carcinomas. Matrix-producing carcinoma is an exceedingly rare form of MBC distinguished by a ductal carcinomatous component with direct transition to areas of cartilaginous or osseous differentiation without the presence of an intervening spindle cell element. MBCs are clinically aggressive, but matrix-producing subtypes have a relatively better prognosis. The tumors are usually triple negative. Therefore, surgery and chemotherapy are the main therapeutic approaches. Our report describes this unique form of MBC with prominent osseous differentiation in a 33-year-old female patient. Its distinct histological features and peculiar clinical behavior necessitate a thorough understanding of this one-of-a-kind disease entity.

RESUMO

Key Clinical Message: A very rare skin cancer. Malignant variant of pilomatricoma. It is unique because of its highly aggressive behavior. Responds poorly to chemotherapy and radiotherapy. Treated with a wide surgical excision with safe margins. Abstract: Pilomatrix carcinoma is uncommon and locally aggressive tumor of the hair follicle matrix. It is a malignant variant of pilomatricoma. If left untreated for a long time may attain massive size and has the potential for distant spread. Only few cases with brain extension have been reported in the literature. Diagnosis of these tumors is established by histopathology. Although pilomatrixoma and pilomatrix carcinoma are well-recognized lesions, clinically they are frequently misdiagnosed as other skin conditions. The tumors respond poorly to chemotherapy and radiotherapy. Thus, recommended treatment is a wide surgical excision with safe margins. Herein, we report the case of a 39-year-old African woman with pilomatrix carcinoma of the scalp eroding the skull bone with intracranial extension.

RESUMO

PURPOSE: An understanding of the cultural and context-specific perceptions of the causes of cancer is an important prerequisite for designing effective primary health prevention and early detection strategies. We aimed to use the Murdock Ill Health Theoretical Model to conceptualize views on illness causation among dysphagia-suffering patients undergoing diagnostic workup for esophageal cancer (EC) in Tanzania. METHODS: At the end of a structured interview on lifestyle habits, patients with suspected EC were asked about beliefs on the reasons behind their illness through (1) a set of questions with fixed binary answers, whose determinants were analyzed using logistic regression, and (2) a single question with free-text answers. Responses were coded using a hierarchy of natural and supernatural (godly and social constructs) causes. RESULTS: Among 322 patients interviewed between November 2015 and December 2019, we found complex and varied views about the origins of their illness. Overall, 49% of patients attributed illness to natural causes and 39% to supernatural causes. Natural causes ranged from infection, use of alcohol and tobacco, other ailments, and the environment. The supernatural causes included attributing illness to God, curses, and spells from personal acquaintances. Belief in supernatural causes was more common in the less educated and those who sought help first via a traditional healer. CONCLUSION: The results underscore the need for increased community awareness of biomedical causes of ill health and patient-based participatory research to inform prevention programs. The results also highlight the importance of building health systems that support a series of health-seeking behaviors that acknowledge both biomedical and local traditional healing belief systems.

RESUMO

INTRODUCTION AND IMPORTANCE: Brain metastasis is the most common associated consequence of primary lung cancers, and it has a major detrimental influence on patients' survival and quality of life. Modern imaging modalities such as brain MRIs and PET scans are preferred for assessing these lesions. Complete surgical resections have been shown to enhance survival. CASE PRESENTATION: We present the case of a 59-year-old male patient who had a history of progressive left-sided weakness and right-sided headaches with no respiratory symptoms. A solitary brain lesion was noticed, prompting a surgical resection. Histology findings confirmed brain metastases, and a thoracic CT scan revealed a primary lung tumour. The patient was scheduled for chemotherapy. DISCUSSION: Primary lung tumors often disseminate to the brain. The brain metastatic lesions in advanced lung cancer are often numerous and smaller in size, based on MRI imaging. The patient's symptomatology obscured the existence of an underlying lung tumour, delaying focused therapy. The early symptomatology and scans of our patient indicated the probability of a solitary brain tumour, necessitating a surgical excision. CONCLUSION: Prompt management of brain metastatic lesions is crucial. Yet, some patients emerge with atypical characteristics of the lesions that hint to a primary brain lesion and conceal the presence of a lung tumour. Enhancing these patients' prognoses necessitates a targeted therapy that includes a comprehensive examination, radiological imaging, and recognition of the distinctive brain patterns in patients with lung cancer. The merits of complete or incomplete resections for multiple brain metastatic lesions might be a fascinating subject of discussion.
