Dengue is known for its nonspecific onset and frequently can rapidly deteriorate into a range of feared systemic complications including hemorrhagic fever and shock syndromes. However, vocal cord hematomas associated with dengue fever are a rare presentation. Here, we describe a case of vocal cord hematoma in a patient with dengue and thrombocytopenia, highlighting this rare association, which has a potential to aggravate into a life-threatening complication. The patient was treated conservatively and made a complete recovery.

| Introduction|| |
A vocal cord hematoma is a collection of blood within the vocal fold that occurs after rupture of blood capillaries. Vocal cord hemorrhage, even with small quantity of blood, can cause discernible voice changes . Production of voice is due to vibration of two small, layered folds of tissue overlying a muscle along with a combination of muscles in and around the larynx by modulating airflow from the lungs. When a bleed into the vocal cord occurs, layers of vocal fold tissue become filled with blood from a ruptured blood vessel, which affects the vibration of vocal cord leading to a change in the quality of voice most often noticeable clinically as hoarseness. Early diagnosis of a vocal fold hemorrhage is very important because of several reasons: primarily, although small, they can result in airway compromise, and second, continuation of phonation with a hematoma can lead to continued bleeding and an irreversible scar of vocal fold and permanent voice change. Here, we describe a case of vocal cord hematoma in a patient with dengue fever and thrombocytopenia who presented with hoarseness of voice. The patient recovered uneventfully after voice rest, intravenous fluid replacement, and platelet transfusion.
| Case report|| |
A 36-year-old male patient presented with presented with the complaints of fever, generalized body pain, tiredness, and sore throat for 4 days. Fever was high grade and not associated with chills and rigors. A day before admission, he developed hoarseness of voice. At presentation, his temperature was 101 °F. He was hypotensive (90/60 mmHg) and bradycardic (50/min) with respiratory rate of 18/min. Hematological parameters showed thrombocytopenia (10 000 cells/mm3) and leucopenia (3100 cells/mm3). Dengue NS1 antigen was positive, liver enzymes and coagulation profile were within normal limits, and chest radiograph result was normal. In view of the voice change, we decided to involve the ENT surgical team. At this point of time, however, the patient was severely thrombocytopenic and so was managed supportively with platelet transfusions. A video laryngoscopy was performed after the patient’s platelets improved, and we were certain of a lowered risk from spontaneous bleeding. The video laryngoscope (VL) showed a hematoma involving both the vocal cords and immediate subglottis ([Figure 1]). He was advised a complete cessation of phonation and given voice rest. His general condition improved and became afebrile. Hemodynamically, the patient improved (platelet count, 70000/mm3) and was discharged at stable condition with advice to follow-up. After 2 weeks, the patient had recovered almost 90% of his voice, but he was not willing for repeat video laryngoscopy. His platelet count was 250000/mm3.

| Discussion|| |
There is now an unquestionable quantum of good quality evidence associating viral and/or dengue-associated thrombocytopenia with bleeding and subsequent hematoma formation . Spontaneous hematomas secondary to dengue fever have been described in other sites like thorax, abdominal cavity, retroperitoneum, muscle parenchyma, joints, and rarely even lingual hematomas have been described ,,,. A vocal cord hematoma due thrombocytopenia in a chronic myeloid leukemia has been reported in the literature . To the best of our knowledge after extensive search, this is the first case of a vocal cord hematoma associated with dengue fever.
Within the vocal folds, there are extremely small tiny blood vessels that extend across the various tissue layers. Vocal cord hemorrhage results from the rupture of a submucosal blood vessel of the vocal fold, releasing blood which diffuses through the low-resistance tissue of the superficial layer of the lamina propria which disrupts the mechanical properties of this tissue, consequently resulting in changes in the vibratory parameters of the affected vocal folds. This can result in severe dysphonia . There are numerous causes for vocal cord hematoma/hemorrhage such as trauma to the larynx after blunt force injury, phonotrauma, active upper respiratory tract infection, complication of medical or surgical procedure, hormonal imbalances, and use of anticoagulant among others .
In the present case, the hematoma was probably due to thrombocytopenia secondary to dengue fever. Platelet count during the time of hematoma was around 10 000 cells/mm3. Our patient, like the familiar presentation of other vocal cord-associated problems, presented with hoarseness of voice and vocal fatigue in addition to his viral prodromal symptoms. In this case, it is essential to establish the diagnosis of vocal cord hemorrhage definitively and early as, in view of the thrombocytopenia, if one continues to talk, further hemorrhage and scarring of the vocal fold layers may result leading to permanent voice changes . Vocal cord hemorrhage can resolve spontaneously or can result in vocal cord polyp or a permanent vocal fold scar . To conclude, in the absence of any other obvious causes for a vocal cord hematoma, we have concluded that the thrombocytopenia and phonotrauma have most likely resulted in vocal cord hemorrhage in our patient. It must be therefore emphasized that vocal cord hematomas should not be ruled out in patients who present with the background of an arboviral hemorrhagic fever and voice change until a laryngoscopic examination has been carried out satisfactorily after the patient’s platelet counts have recovered to safe ranges.
