Deep penetrating nevus: a case report and brief literature review.

ABSTRACT:

Background

Deep penetrating nevus (DPN) is a distinct variant of melanocytic nevus and remains a histopathologic challenge to pathologists because of its resemblance to blue nevus, malignant melanoma, pigmented Spitz nevus, and congenital melanocytic nevus. It often goes unrecognized due to its relative rarity.

Case presentation

Here we report a case of DPN of the left anterior leg in a 51-year old female. A brief review of the literature shows that these lesions have a distinct growth pattern and cellular morphology that can differentiate these lesions from other entities including malignant melanoma.

Conclusion

It is important to recognize these features because DPN carries a better prognosis than malignant melanoma.

Treatment and molecular analysis of bullous pemphigoid with tofacitinib: a case report and review of current literature

Project description:Bullous pemphigoid (BP) is a rare, life-threatening autoimmune blistering disease with pruritus and tension blisters/bullous as the main clinical manifestations. Glucocorticosteroids are the main therapeutic agents for it, but their efficacy is poor in some patients. Tofacitinib, a small molecule agent that inhibits JAK1/3, has shown incredible efficacy in a wide range of autoimmune diseases and maybe a new valuable treatment option for refractory BP. To report a case of refractory BP successfully treated with tofacitinib, then explore the underlying mechanism behind the treatment, and finally review similarities to other cases reported in the literature. Case report and literature review of published cases of successful BP treatment with JAK inhibitors. The case report describes a 73-year-old male with refractory BP that was successfully managed with the combination therapy of tofacitinib and low-dose glucocorticoids for 28 weeks. Immunohistochemistry and RNA sequencing were performed to analyze the underlying mechanism of tofacitinib therapy. A systematic literature search was conducted to identify other cases of treatment with JAK inhibitors. Throughout the 28-week treatment period, the patient experienced clinical, autoantibody and histologic resolution. Immunohistochemical analysis showed tofacitinib significantly decreased the pSTAT3 and pSTAT6 levels in the skin lesions of this patient. RNA sequencing and immunohistochemical testing of lesion samples from other BP patients identified activation of the JAK-STAT signaling pathway. Literature review revealed 17 previously reported cases of BP treated with four kinds of JAK inhibitors successfully, including tofacitinib (10), baricitinib (1), upadacitinib (3) and abrocitinib (3). Our findings support the potential of tofacitinib as a safe and effective treatment option for BP. Larger studies are underway to better understand this efficacy and safety.

Lemierre's syndrome: Case report and brief literature review.

Project description:Lemierre's syndrome has been shown to be increasing in incidence in the past 20 years with one popular suggesting that said rise occurred from less aggressive antibacterial coverage. We report a case of Lemierre's syndrome and also reviewed the 15 most recent case reports. A previously healthy 25 year old male who initially developed sore throat and flu-like symptoms, was prescribed antibacterials as an outpatient but was hospitalized for worsening symptoms. He was later diagnosed with Lemierre's syndrome and improved clinically with IV antimicrobials alone. From our concise literature review, we determined that a decrease in antibiotic prescriptions may not fully explain why the incidence of Lemierre's has been increasing. Thus, future research should be focused in evaluating possible worsening susceptibilities to antibiotics and improvements on detection. We also advise physicians to be aware of the signs and symptoms of this rare but potentially fatal condition as well as the available detection methods and treatment.

Blue Rubber Bleb Nevus Syndrome With Multiple Cavernoma-Like Lesions on MRI: A Familial Case Report and Literature Review.

Project description:Blue rubber bleb nevus syndrome (BRBNS), also called Bean's syndrome, is a rare disease associated with multiple venous malformations in the skin and gastrointestinal (GI) tract. Dermatological lesions, which are the first clinically visible manifestations, appear as skin-colored compressible protuberances or as dark-blue venous nodules, rubbery in consistency. Central nervous system (CNS) manifestations are rare, variable, non-specific, and tend to occur late in the disease, mainly reported as seizures and focal neurological deficits secondary to compression. Most cases occur sporadically, however, an autosomal dominant inheritance pattern has been reported. A 74-year-old male with history of focal epilepsy secondary to possible neurocysticercosis presented at the emergency department due to sudden onset of aphasia, left central facial paralysis, and dysphagia secondary to catastrophic intracerebral hemorrhage. Cerebral MRI showed multiple cerebral cavernous malformations (CCM)-like lesions and, on the general exploration, multiple dark-blue nodules, rubbery in consistency. One week later he died due to complicated pneumonia; a brain autopsy was performed showing multiple vascular malformations. His son had a history of focal epilepsy presumed to be related to neurocysticercosis. He had the same skin lesions and brain MRI pattern. Histological analysis of the skin lesions of the two cases showed venous vascular malformations. A non-systematic review was carried out, in which all case reports of blue nevus syndrome with neurological manifestations in adults were included.

Rare Type Cranial Postauricular Pilonidal Sinus: A Case Report and Brief Review of Literature.

Project description:A pilonidal sinus is a chronic inflammatory process, the etiology of which is still not fully elucidated. It frequently presents at the sacrococcygeal region (typical) and rarely at extrasacrococcygeal (atypical) locations, including the interdigital, axillary, inguinal, and umbilical regions, as well as the neck, face, and scalp. A 46-year-old man presented with a thirty-year history of a slowly growing nodule on the postauricular area of the scalp. The lesion was excised and diagnosed as a pilonidal sinus based on the clinical and histological findings. The purpose of this review is to report the unusual occurrence of a pilonidal sinus on the scalp and to review the literature regarding this particular location of occurrence.

Orbitocranial Penetrating Injury With Multiple Vessel Invasion in an Infant: A Case Report and Literature Review.

Project description:Orbitocranial penetrating injury (OPI) with multiple vascular invasions is a rare occurrence. To our knowledge, experience with its clinical treatment is rather limited, especially for infants. This case report describes an infant who fell from a 0.5 m high bed and landed on a toy with a keen-edged plastic rod. The fractured end of the rod was noted at the medial aspect of the left eyelid, and she was experiencing impaired consciousness. Computed tomography showed that the foreign body penetrated the cavernous sinus with internal carotid artery involvement, and compressed the transverse sinus through the cerebellum. Emergency surgery was performed with temporal occlusion of the left common carotid artery. The rod was removed from the orbital side, and bleeding from cavernous sinus region was effectively controlled under direct inspection via a sub-temporal approach. The patient was successfully treated and recovered consciousness after 17 days. This is the first report of successful management of OPI combined with multiple vascular injury in an infant. Herein, we highlight the anatomical imaging features of the injuries and also the individualized strategy concerning vascular invasion.

Blue Rubber Bleb Nevus Syndrome with Long-Term Follow-Up: A Case Report and Review of the Literature.

Project description:Blue rubber bleb nevus syndrome (BRBNS) is a rare disease in which venous malformations (VMs) involve any body organ, most commonly the skin and the gastrointestinal (GI) tract. Treatment of BRBNS aims at preserving the GI tract as much as possible. Although there are several dozen case reports about BRBNS that describe short-term clinical courses, a few provide an account of long-term clinical course. Here, we report a case of BRBNS in a girl that required multiple abdominal surgeries due to the GI VMs and a recurrence at an interval of 14 years. The preferred approach for gastrointestinal VMs involves the complete resection of all lesions without residual VMs. It is important to bear in mind the possibility of delayed recurrence of GI VMs after surgical or endoscopic treatment.

Mixed acinar-endocrine carcinoma of pancreas: A case report and brief review of the literature.

Project description:Mixed acinar-endocrine carcinoma (MAEC) of the pancreas is a rare entity. We present a 65-year-old Chinese female who was admitted with jaundice and nagging epigastric pain with intermittent diarrhea for 1 month. She eventually underwent abdominal magnetic resonance imaging, which showed an 8×6 cm mass in the head of the pancreas and showed two abnormal lesions in the liver simultaneously. MAEC of the pancreas with synchronous hepatic metastasis was confirmed with immunohistochemistry after Whipple operation and hepatic partial resection of the lesions. Postoperative recovery of this patient was uneventful, and no evidence of recurrence or metastasis was observed after 12 months of follow-up. MAEC of pancreas is thought to be extremely rare and lack of typical clinical symptoms. The prognosis is poor overall, but early detection with complete resection may be beneficial to patients.
