Ecchymosis in critical coronavirus disease 2019 (COVID-19) patient in Tangerang, Indonesia: a case report.

We have read with great interest the articles regarding cutaneous manifestations in Coronavirus Disease 2019 (COVID-19) infection. Studies showed 20.4% of COVID-19 patients developed cutaneous manifestations. COVID-19 causes vascular endothelial injury, vasculitis and prothrombotic state which might be the underlying cause of hemorrhagic cutaneous manifestations, disseminated intravascular coagulation (DIC), and multiple organ failures. To date, hemorrhagic cutaneous manifestations reported are chilblain-like lesion, purpura to ecchymosis, livedo reticularis, and dry gangrene. We present a case of ecchymosis in COVID-19-positive ICU hospitalized patient.

Late Occurrence of Raccoon Eyes: The Role of the Ligature.

This case represents a planned complex suicide in which the victim combined gunshot to the head and hanging. The most interesting finding in the presented case was pale face, but without any visible injury to it at the time the body was found (more than 24 hours after death), whereas at autopsy (20 hours later), black eyes were prominent. The removal of the ligature led to the decompression of the neck and its blood vessels with consequential blood redistribution, which, alongside the liquid state of blood, resulted in the aforementioned finding. Considering the described postponed appearance of periorbital ecchymosis, this kind of finding suggests that great caution is necessary when interpreting hematomas in terms of their vitality.

Fatal entrapment in a pool drainage system: a case report.

Swimming pool suction injuries are rarely encountered in forensic medicine. Infants under 8 years of age are most frequently involved in such accidents with high risk of serious injuries and fatal consequences due to drowning. We report, for the first time, a case of a 13-year-old boy trapped at the abdomen by an uncovered suction drainage hole. External examination of the body revealed a round ecchymosis which had the same diameter as the pool drain. Post-mortem examination established that death had occurred due to drowning, possibly in combination with traumatic shock from the suction mechanism involving the intestinal loops. Furthermore, this case may be remarkable as it raises other medico-legal issues regarding the safety standards at swimming pools, including pool management and lifeguard attendance. Preventative measures are needed in order to make sure this sort of injury or death does not occur. Moreover, the awareness of the occurrence of these accidents should be increased.

Chest wall hematoma after central venous hemodialysis catheter insertion.

There were few case reports discuss about iatrogenic chest wall hematoma. Although it is rare life threatening, it still can result in significant morbidity. A 68-year-old woman with histories of end-stage renal disease under regular hemodialysis and congestive heart failure was sent to our emergency department because of progression of ecchymosis over the anterior chest wall a few hours after hemodialysis. The right subclavian hemodialysis catheter was inserted for hemodialysis on the same day. She did not have a history of bleeding disorders and was not taking any antiplatelet or anticoagulant agents. Additionally, she had no recent trauma episodes. Physical examination revealed a large ecchymosis over the anterior right chest wall with swelling and tenderness. Blood examination showed no specific finding. Contrast-enhanced computed tomography of the chest revealed a hyperdense lesion with extravasation over the right chest wall, suggesting the presence of a hematoma with active bleeding. Local compression was applied. However, hematoma expansion was still noted. Therefore, we consulted a thoracic surgeon concerning surgical intervention. During the operation, active bleeding of the intramuscular arterial branch of the right pectoralis major was encountered. After surgical repair, no more bleeding was noted. It is important to confirm the possible cause of chest wall hematoma. Treating the underlying disease and discontinuing anticoagulation and antiplatelet agents should be considered. For iatrogenic chest wall hematoma, bleeding control should be the priority. Contrast-enhanced computed tomography could be arranged if there are no contraindications.

Physical Findings Mimicking Sexual Abuse in a Drowning Patient Who Was Treated in the Intensive Care Unit: A Report on a Fatal Case.

Specific or nonspecific findings of sexual abuse may be observed upon examination of a child. Examination of the genital area is extremely important for the identification of child sexual abuse (CSA). However, medical conditions detected in the child's genital area may be misinterpreted as signs of CSA. Herein, we present a case of a child with suspected CSA who was treated in the intensive care unit. The following incidental findings were obtained upon anal examination: dilatation, ecchymosis, laceration, and hemorrhage. This report aims to discuss the anal examination findings that can mimic CSA.

Dermatological Implications of Coining: An Eastern Medicine Cultural Practice.

A 36-year-old Chinese man with no significant medical history presented to his clinician's office for follow-up of results from recent blood work. Upon entering the room, the patient was wearing a mask. After reviewing his lipid panel, he mentioned that he had been "fighting a cold." He reported 3 days of cough with chest tightness and mild shortness of breath. He denied fever. The patient was using an overthe- counter cough medicine but reported no chronic medication use. On initial inspection, the patient had a vivid purple eruption on his arms. The patient denied pain or itching. After the patient lifted his shirt, the full extent of the discoloration was seen configured in a symmetric fashion over the anterior torso and abdomen (Figure 1). The eruption was purple-red in color and distributed in a linear pattern over the anterior chest contouring the outline of the underlying ribs. Additional vertically arrayed areas of erythematous skin consisting of microecchymoses were appreciated on the anterior abdomen. These appeared to follow an intentional pattern. No other petechiae, palpable purpura, or isolated ecchymoses were seen. When questioned further, our patient readily admitted that he had participated in a common traditional Chinese treatment consisting of "scraping bruises" to relieve his bronchitis.

[Painless skin nodules and ecchymosis in a school-aged girl].

A 7-year-old girl was admitted to Xiangya Hospital due to systemic lymphadenectasis for 2 months and skin ecchymosis for 3 days. Nine months ago, the girl experienced painless nodules in the left lower extremity with no apparent causes. Three months later, dermatorrhagia and ecchymosis occurred in many regions such as the periocular areas, conjunctiva, oral mucosa, perineal area, and groin, with a "raccoon sign" in both eyes; superficial lymphadenectasis and hepatosplenomegaly were also observed in many regions. The pathological sections for the skin nodules showed malignant tumors in lymphohematopoietic cells, and in combination with clinical manifestations, immunohistochemistry, and positive results for CD4, CD56, and CD123 by bone marrow flow cytometry, the girl was diagnosed with blastic plasmacytoid dendritic cell neoplasm. Then high-risk ALL regimen was applied as the chemotherapy for this girl. At present, the girl has been followed up for 3 months; ecchymosis has disappeared, and the enlarged lymph nodes have shrunk. No abnormal cells have been found in bone marrow morphological examination, and bone marrow flow cytometry has shown that primitive precursor cells account for 1.5% and express CD33, CD34, CD123, and CD117.

Superficial hemosiderotic lymphovascular malformation (hobnail hemangioma): a report of six cases.

Hobnail hemangioma (HH), initially termed targetoid hemosiderotic hemangioma, is a rare, often solitary lesion classically characterized by a central brown or violaceous papulonodule surrounded at times by an ecchymotic halo. This lesion is typically found on the trunk or limbs of children or young to middle-aged adults. Numerous case reports have found HHs to have a reproducible histologic appearance. Although the exact histogenesis of these lesions is unknown, multiple recent immunohistochemical studies suggest a lymphatic origin of these lesions. We present six cases of children with HHs with classic histology but with variability in their clinical appearance. Because the clinical presence of a targetoid halo is inconsistent and the hobnail phenomenon is not specific, we favor the designation of superficial hemosiderotic lymphovascular malformation instead of HH or targetoid hemosiderotic hemangioma as a more unifying term for this rare clinical entity. By eliminating confounding terminologies (in this case, incorporation of "hemangioma" in the name of this entity), we also hope to encourage a swifter change in practice to move away from erroneous diagnostic considerations.

Pathological findings in 2 cases of fatal 25I-NBOMe toxicity.

The research compound 25I-NBOMe, also known as CIMBI-5 or INBMeO, was created in academic laboratories as a potent serotonin 2A receptor agonist. Because of its high affinity and ambiguous legal status, recreational drug enthusiasts have used this compound as a powerful alternative to other hallucinogenic drugs such as lysergic acid diethylamide. We report 2 deaths after 25I-NBOMe ingestion by decedents who attended separate "rave" parties. The first case involved a 21-year-old male who admitted taking "acid" to his friend. A sudden violent rage caused him to flail about, and he subsequently became unresponsive. The postmortem examination revealed numerous external injuries that were consistent with physical aggression. The second case involved a 15-year-old female who was socializing outside a rave party, became ill, and rapidly deteriorated as her friend transported her to the hospital. The postmortem assessment was similar to the first case in that external contusions featured prominently. Comprehensive toxicology screens in both cases revealed only evidence of marijuana use. A deeper analysis using time-of-flight mass spectrometry revealed the presence of 25I-NBOMe, which was further confirmed by tandem-mass spectrometry. The behavior and injuries in these cases reveal a consistent pattern preceding fatal 25I-NBOMe toxicity.

Evaluation of shotgun suicides in Konya, Turkey between 2000 and 2007.

The number of the suicides is increasing all around the world. In this study, the cases autopsied between 2000 and 2007 in The Konya Branch of Forensic Medicine Council were retrospectively investigated. Fifty-seven shotgun suicides were determined. The cases were evaluated in terms of their demographic characters, site of entrance wound, the type of the cartridge used, shooting distance, the place of incident, the place of death, motive for suicide, and the presence of previous suicide attempts. The most preferred site of entrance wound was the head with 34 cases (59.7%). Of 34 cases in which the entrance wound was on the head, there was indirect mandibular fracture in 16 cases (47.1%). In 11 cases (19.3%), there observed small ecchymosed abrasions on the finger surfaces, which are thought to have resulted from the trigger kicking back during triggering or the finger having been stuck between the trigger and the trigger guard. It is concluded that there is a need for a legal regulation that makes obtaining of shotguns more difficult and the people who have them are to be educated not to keep them in easily accessible places.

Neck pseudo-bruising secondary to acute aortic dissection.

We report a case of lethal acute aortic dissection revealed by a large ecchymotic area at the root of the neck; the subject was an 86-year-old man who died suddenly in his hospital room. His medical history included ischemic heart disease with pacemaker implantation and an aortic surgical prosthesis. Forensic autopsy showed a major subcutaneous hemorrhage in the neck and large left pleural and pericardial adhesions secondary to thoracic surgery. The cause of death was an acute aortic dissection. Large adhesions led to an extensive mediastinal hemorrhage, spreading to the subcutaneous tissues of the neck. This case report highlights the difficulties in differentiating between traumatic and pseudo-bruising during a death scene investigation. The etiologies of pseudo-bruising are reviewed.

Fatality in a wine vat.

Intoxication with carbon dioxide (CO2), a nonexplosive, colorless, and odorless gas does not cause any clinical symptoms or signs, with the occasional exception of sudation. Carbon dioxide is principally used in the food industry (70% of CO2 production), in particular to preserve foods and to carbonate beverages. Most fatalities resulting from CO2 intoxication are accidental and occur either in closed spaces or when dry ice is used in the food industry. In this case report, a 42-year-old male winemaker engineer was found dead, his head inside a wine vat that had been filled with grapes on the previous day and supplemented with dry ice to improve the taste of wine.

Anatomopathological findings in hangings: a retrospective autopsy study.

BACKGROUND: In this retrospective autopsy study, we aimed to review the anatomopathological findings observed in cases of hanging death for a five year period and to evaluate the role of contributing factors such as age, sex, type of hanging and localization of the ligature knot. METHODS: Autopsy reports of 102 hanging cases performed by the Department of Forensic Medicine, Faculty of Medicine of Pamukkale University, between January 2007 and September 2011, were retrospectively reviewed. RESULTS: In the 102 hanging cases 73 of the victims were males (71.6%) and 29 (28.4%) were females, with a mean age of 40.97 ± 17.41 years. All cases were suicidal hanging. Fifty four cases (52.9%) were typical hanging, with the ligature knot located posteriorly. There were petechial hemorrhage on the face and eye lids in 46 (45.1%), ecchymoses of the cervicale muscles in 43 (42.2%), and fractures of the neck structure(s) in 69 cases (67.6%). CONCLUSIONS: The incidence of neck structure fractures increased with age. In addition, there was no correlation between the incidence of neck structure fractures and sex or type of hanging.
